>> bye. >> mason: the white house shake-up and a lovefest. averell spicer is out. >> and i love the guy. >> mason: anthony scaramucci joins the communications team. >> i love these guys. >> mason: and the message of the day: >> i love the president. i love the president. >> i love the president. >> mason: also tonight, fighting alzheimer's. a new study says start early. >> everyone, today, right now, can grab the bull by the horns and can say, i can do something today to reduce my own risk. >> mason: is this the future? new york to washington in less than a half hour underground. and steve and andrea hartman in "return to green acres." >> he goes out at 7:00 at night and weeds until dark. sometimes he's out there past dark.

captioning sponsored by cbs this is the "cbs evening news." >> mason: good evening. i'm anthony mason. president trump shook up his communications team today. he brought in new york financier and one-time critic anthony scaramucci to head it up. sean spicer is out as press secretary. and deputy sarah huckabee sanders was promoted to chief spokesman for a president who often prefers to speak for himself. with mr. trump's job approval at an all-time low and his agenda in jeopardy, scaramucci's goal will be taking the mess out of the messaging. here's major garrett. >> this is obviously a difficult situation to be in. >> reporter: that's stating the obvious. anthony scaramucci knows wall street and has close ties to president trump and his family, but his arrival prompted press secretary sean spicer to resign and flared long-simmering tensions with chief of staff reince priebus and chief

strategist steve bannon, both opposed his hiring. typically a communications director is subservient to the chief of staff and a top strategist, but scaramucci will not have to check in with priebus or bannon. >> the president said i report to him directly. >> reporter: that's a victory, one denied when scaramucci was left off the president's roster of top appointees after the inauguration. >> you weren't a significant player during the transition. was it disappoint thank you did not land a post from the get-go? >> was i disappointed, yes. i've said that candidly. but i love the president, and i'm very, very loyal to the president. >> reporter: scaramucci donated money to barack obama and hillary clinton and he deleted tweets favorable about them. he was reminded of this oust burst. >> he's a hacker from queens county. bring it, donald. >> he brings it up every 15 seconds. i should never have said that. mr. president, if you're

personally listening, i apologize for the 50th time for saying that. >> reporter: deputy press secretary sarah huckabee sanders will all right to scaramucci as the press secretary. spicer suffered credibility problems, starting on inauguration day. >> this was the largest audience to ever witness an inauguration period. >> reporter: reaching a career low with this statement about syria's use of chemical weapons and subsequent apology. >> you had a, you know, someone as despicable as hitler who didn't even sink to using chemical weapons. to make a gaffe and a mistake like this is inexcusable and reprehensible. >> reporter: but comedy gold for "saturday night live." >> okay. first of all, here's trump. okay. he's the biggest one and he's the most beautiful. >> reporter: scaramucci says president trump has really good karma and remains the best communicator inside the white house and as such scaramucci said he will not discourage

mr. trump from continuing to use twitter and other social media platforms. one last thing: scaramucci said there is a distinct media bias against this president, something he said he hopes to "de-escalate." anthony? >> mason: major garrett at the white house. thank you, major. one of the biggest issues facing scaramucci is the russia investigation. the president has been critical of the special counsel and has the power to fire him, but so far mr. trump is just firing at him. here's julianna goldman. >> reporter: even with president trump's attacks on the special counsel front and center, newly installed white house communications director anthony scaramucci punted. is the strategy that seems to be coming from this white house now in going after robert mueller's credibility the right one? >> again, that is sort of in that zip code of like, you know, the legal team. >> reporter: yet mr. trump and his team have been laying the groundwork to undermine robert mueller's investigation for weeks. >> i can say that the people

that have been hired are all hillary clinton supporters. >> reporter: mueller's first four hires, one worked for the clinton foundation, all four donated to the democrats. >> people should know folks' pasts and their motivations and what their political motivations are. >> reporter: mr. trump is taking on a team of all-star prosecutors they even his own allies concede are some of the best in the business. discrediting parties involved in a legal dispute is a new frontier for president trump, but it's a method he's employed repeatedly over the course of his business career. last year mr. trump called a woman who accused him of sexual assault sick and horrible. in 2007 he called the defendant a sleazebag. during the campaign he repeatedly said the judge in the trump university case had a conflict because of his mexican heritage. >> the judge, who happens to be, we believe, mexican... >> reporter: and mr. trump and his team tried to discredit plaintiffs who were former students in the case. when we discussed trump university with the trump

organization attorney in 2015, he brought folders bearing the names of former students critical of the defunct program, but now the stakes couldn't be higher, and he's trying to discredit the special counsel. a fellow republican who was praised by none other than neutropenia who tweeted that mueller's reputation is impeccable for honesty and integrity. in a 2007 book, mr. trump wrote that he loves getting even. the white house maintains the president has the power to fire mueller at any point. the special counsel's office declined to comment. anthony? >> mason: julianna goldman, thanks. members of congress have a member for the president: don't antagonize the special counsel. you can regret it. here's nancy cordes. >> it would prompt a fighter storm. >> reporter: members of both parties are warning the president not to mess with mueller. >> firing bob mueller without cause is an attack on the rule of law. >> reporter: it sort of looks

paranoid to me. >> reporter: republican michael mccaul chairs the house homeland security committee. >> if he fired bob mueller, i think you would see a tremendous backlash response from both democrats, but also house republicans. >> reporter: respect for mueller runs deep on capitol hill, especially among republicans. he was george w. bush's pick for f.b.i. director and served throughout the bush presidency. >> i think the best advice would be to let robert mueller do his job. >> reporter: republicans were also stunned by the president's slam on their former senate colleague, who is now attorney general. >> jeff sessions takes the job, gets into the job, recuses himself, which frankly, i think is very unfair to the president. >> reporter: iowa's chuck grassley says sessions was right to recuse himself. >> the attorney general can't be a wing man for a president. he has to be very independent. >> reporter: as for those threats to dig up dirt on

mueller and his staff, florida's marco rubio says good luck. >> i don't think it's going to influence bob mueller's work one way or the other. i'm pretty confident just knowing him and knowing the way he conducts himself. he doesn't wake up in the morning and read those things and have it impact his ability to do his job. he's going to do his job. >> reporter: some republican aides praised the new choice for white house communications director today, emphasizing his poise and kris mark but others complained to us that he has no experience with communications strategy or planning, something they say the white house badly needs, anthony. >> mason: nancy cordes at the capitol. thank you, nancy. we turn now to john dickerson, our chief washington correspondent and anchor of "face the nation." john, as nancy pointed out, robert mueller enjoys an excellent reputation almost everywhere it seems except the white house. is this strategy risky for the trump team? >> well, the risk for the trump team is that they make these claims, raise these issues about

robert mueller and you get immediate validation of mueller's work by republicans. so if the president wants to say it's a witch-hunt, then you have marco rubio and paul ryan, you know, republican voices saying it's not, they trust him, it's sort of... it reenergizes the legitimacy of the work that mueller is doing. when the president went after former f.b.i. director james comey and said a number of highly critical things, saying he lied, it was interesting that very few republicans followed him along in that. so it puts the president out on an island. and this is a way in which anthony scaramucci's job will be a challenge. these comments the president made to the "new york times," they help preserve the president perhaps in terms of trying the weaken anybody who would attack him, but it absolutely gets in the way of the president's agenda, the things he wants to do for the people who elected him, because the stories are a distraction and they... republicans have to deal with them instead of dealing with healthcare or infrastructure or tax reform. and so one of the things that

scaramucci may do is just keep the president restrained and try to keep the communication about the issues. >> mason: john, as major reported, there was resistance within the west wing to the scaramucci appointment. so does this change the power structure in the white house at all? >> it does. it could change it in a positive way. scaramucci is a self-made man. he's a successful businessman. he can talk to the president with some ballast from that experience, and that might get the president to perform in a way that the collective group at the white house, that the team wants him to kind of stay on message, stay in the strategy. on the other hand, the more people who can just walk into the oval office and talk to the president, the more that a president can shop for views that he likes, that can undermine the rest of the operation and in a place where everybody can go see the president, they sometimes worry about people doing things behind their back. >> mason: john dickerson, thanks. and john's guest on "face the nation" this sunday include congressman adam schiff, the top democrat on the house

intelligence committee, and republican senator susan collins of maine. in the middle east, at least six people were killed today in clashes between palestinians and israelis. anger boiled over when the israeli government tightened security at one of jerusalem's holiest sites. jonathan vigliotti is following this. >> reporter: the clashes erupted after friday prayers a few streets away from the al-aqsa mosque compound in jerusalem. israeli soldiers fired stun grenades and tear gas at palestinian worshipers, some of whom were throwing rocks and firebombs. thousands of palestinians had gathered to protest the new israeli security measures at the compound, sacred to both jews and muslims. the new measures mettle detectors and hundreds more police were added after two israeli policemen were shot dead last week. tensions turned deadly today. two palestinian teenagers were shot and killed in jerusalem, and a third man was killed in

the west bank. hundreds were injured and more than two dozen arrested. five israeli security forces were wounded. palestinians have long accused israel of trying the take control of the sacred site, and the new security measures were the last straw. it's unclear how long the detectors will remain in use. the israeli government insists they're meant to prevent future attacks, but anthony, police say three israelis were stabbed to death tonight in what appears to be retaliation. >> mason: jonathan vigliotti tonight, thanks. now to the battle against alzheimer's disease. a new study says making lifestyle changes today can make a big difference tomorrow. here's jon lapook. >> reporter: it's the most come hencive report saying fighting dementia can start when you're young. in early life, maximize education. in middle age, aggressively treat hypertension, obesity, and hearing loss, and in later life,

manage depression, diabetes, smoking, and loneliness. dr. richard isaacson is director of the alzheimer's prevention clinic at weill cornell >> alzheimer's starts in the brain 20 years before memory loss. that leaves ample time to make changes. >> reporter: one patient is jack fishbaum, who is fighting the early stages with dementia with lifestyle changes and the occasional joke. >> any dreams? >> i had a crazy dreams last night. i dreamt i was a muffler and i woke up exhausted. >> reporter: but he also counsels 36-year-old isaac brody, whose family history concerns him. >> my grandfather passed away from dementia. >> reporter: is it the back of your head, this is something you want to avoid? >> you want to be healthier and feeling good. >> reporter: it's now. the time is to talk about alzheimer's prevention.

everyone today, right now can, grab the bull by the horns and can say, i can do something today to reduce my own risk. >> reporter: it's very human to want to put off lifestyle changes to tomorrow, but this report supports a growing evidence that what you do today can make a huge difference when it comes to preventing dementia. anthony? >> mason: dr. jon lapook, thanks. still ahead on the "cbs evening news," imagine new york to d.c. in less time than it takes to watch this broadcast. and steve hartman's war on weeds. about the client dinner. you gonna wear? hannah. did you get that email i sent you? i need you to respond... ...before you wake up. when life keeps you up... zzzquil helps you fall asleep in less than 20 minutes. because sleep is a beautiful thing.

but their nutritional needs (vremain instinctual.d, that's why there's purina one true instinct. nutrient-dense, protein-rich, real meat number one. this is a different breed of nutrition. purina one, true instinct. i hafor my belly painking overand constipation.ucts i've had it up to here! it's been month after month of fiber. weeks taking probiotics! days and nights of laxatives, only to have my symptoms return. (vo) if you've had enough, tell your doctor what you've tried and how long you've been at it. linzess works differently from laxatives. linzess treats adults with ibs with constipation or chronic constipation.

it can help relieve your belly pain, and lets you have more frequent and complete bowel movements that are easier to pass. do not give linzess to children less than six, and it should not be given to children six to less than 18. it may harm them. don't take linzess if you have a bowel blockage. get immediate help if you develop unusual or severe stomach pain, especially with bloody or black stools. the most common side effect is diarrhea, sometimes severe. if it's severe, stop taking linzess and call your doctor right away. other side effects include gas, stomach-area pain, and swelling. talk to your doctor about managing your symptoms proactively with linzess. >> mason: how would you like to have breakfast in new york and be at your desk in d.c. in time for your morning coffee break? a tech entrepreneur has come up with a plan so audacious we had to have kris van cleave check it out. >> reporter: if tech entrepreneur elon musk has his way, it will only take 29 minutes to commute between new

york and washington one day, traveling on something like an ultrafast underground train. musk, the founder of tesla and spacex tweeted yesterday he just received verbal government approval to build a hyperloop tunnel connecting manhattan, philadelphia, baltimore, and d.c. adie tomer. >> it's a testament that we're talking about this idea today that's decades away. >> reporter: maybe, but several companies are already working to make the hyperloop a reality. one completed a special test on a track completed in the nevada desert. in 2013 musk dreamed up the idea of the loop. the d.c.-to-new york loop would be the world's longest tunnel with trains traveling at 700mph. airliners fly closer to 500, and america's fastest passenger train tops out at 150.

if it gets built, it would be a game changer. >> all of a sudden folks who have family and friends in washington can work in philadelphia and new york on a daily basis. >> reporter: hyperloop is capturing our imagination because the thought of moving at such rapid speeds is nothing short of exciting. hyperloop would still require federal, state, and local approvals and the cost would likely be staggering, in the tens of billions, but still, elon musk has a track record of turning the seemingly impossible into a success. anthony? >> mason: that would be my kind of commute. kris van cleave, thanks. up next, tourists resorts hit by up next, tourists resorts hit by a deadly earthquake. g yes. so let me ask you this... how does diabetes affect your heart? it doesn't, does it? actually, it does. type 2 diabetes can make you twice as likely to die from a cardiovascular event, like a heart attack or stroke. and with heart disease, your risk is even higher. you didn't know that. no.

yeah. but, wait, there's good news for adults who have type 2 diabetes and heart disease. jardiance is the only type 2 diabetes pill with a lifesaving cardiovascular benefit. jardiance is proven to both significantly reduce the chance of dying from a cardiovascular event in adults who have type 2 diabetes and heart disease and lower your a1c. jardiance can cause serious side effects including dehydration. this may cause you to feel dizzy, faint, or lightheaded, or weak upon standing. ketoacidosis is a serious side effect that may be fatal. symptoms include nausea, vomiting, stomach pain, tiredness, and trouble breathing. stop taking jardiance and call your doctor right away if you have symptoms of ketoacidosis or an allergic reaction. symptoms of an allergic reaction include rash, swelling, and difficulty breathing or swallowing. do not take jardiance if you are on dialysis or have severe kidney problems. other side effects are sudden kidney problems, genital yeast infections, increased bad cholesterol, and urinary tract infections, which may be serious. taking jardiance with a sulfonylurea or insulin may cause low blood sugar. tell your doctor about all the medicines you take and if you have any medical conditions. so now that you know all that,

>> mason: we end the week with steve hartman on the road to recovery. >> reporter: you may remember a couple years ago i confessed to a weed addiction. although i only did it at my place in upstate new york, after the kids were in bed, the fact was -- here we go -- i could not stop pulling the things. oh, yeah. oviemugwort, canada thistle, and leafy goldenrod were some of my favorites. i realized the extent of my addiction only after my camera man interviewed my wife andrea about it. >> he goes out at 7:00 at night and weeds until dark. sometimes he's out there past dark. >> reporter: and her point is? >> it's not weeding a garden, it's weeding five acres. >> reporter: four and a half, technically. see, a few years earlier i had this idea, to turn this weedy hillside into a beautiful prairie full of native wild flowers and grasses. i contacted this man, who would

eventually become my dealer. >> we started with prairie. >> reporter: neil diboll owns the prairie nursery in westfield, wisconsin. he got me hooked with purple coneflower, compass plant, and smooth aster. >> i was trying to get you hooked, yes, my product is highly addictive. it's called love of nature. >> reporter: but here's the problem: before you see those flowers in the magazine, you often need to spend a great deal of time weeding a new prairie meadow, and neil made no mention of how addicting that cube. i would come out here every night and dread it. then a switch flipped, and i started coming out here and loving it. >> reporter: weed canning induce a meditative state, and that's therapy for all of us in this crazy world you live in when you can tune everything out and focus on one single minded purpose. >> reporter: also, just as a practical matter, after investing hundreds of hours out here, what else can you do? just give up on the whole project? >> it would...

>> reporter: andrea? >> i could live without it. >> you want your husband back? >> reporter: i don't know if i could live how defeated my husband would feel in f we gave it up. >> reporter: after this story first aired in 2015, i thought a lot about her hesitation. i realized you can take a hobby too seriously. which is why i am now a recovering weedaholic. oh, i'll still clip the occasional spotted knapweed, but i don't obsess like i used to, choosing instead to focus more on these three blossoms, gross like weeds, in the only garden we tend that truly matters. steve hartman at home in catskill, new york. >> mason: the occasional spotted knapweed. steve hartman, a way with words and a way with weeds. that's the "cbs evening news." i'm anthony masonnen i'll see you tomorrow on "cbs this morning" saturday. thanks for watching. have a great weekend. captioning sponsored by cbs captioned by media access g
