5:00. >> ahead at 6:00 an emotional battle over a long running neighborhood taco truck. that's coming up. capt nsored by cbs it mason: a white house shake-up and a lovefest. sean spicer is out. >> and i love the guy. >> mason: anthony scaramucci unins the communications team. ys i love these guys. >> mason: and the message of the ony: >> i love the president. enlove 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." as 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. i mean sometimes he's out there past dark.

this is the "cbs evening news." >> mason: and this is our western edition. 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 havious. anthony scaramucci knows wall street and has close ties to hiesident trump and his family, but his arrival prompted press picretary sean spicer to resign and flared long-simmering wnsions 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 disappointing that you did not land a post from the get-go? >> was i disappointed, yes. thve said that candidly. that i was disappointed. 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 deleted favorable tweets about them, as well as ones critical of mr. trump. and he was reminded of this outburst in 2015. he he's a hack. you're an inherited money dude from queens county. bring it, donald. he brings it up every 15 seconds. i should never have said that. so mr. president, if you're listening, i personally

apologize for the 50th time for saying that. >> reporter: deputy press secretary sarah huckabee sanders will report to scaramucci as the thw press secretary. replacing spicer, who drew great ratings, but also suffered credibility problems, starting on inauguration day. >> this was the largest audience to ever witness an inauguration ceriod. inaugorter: 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 >> ourday night live." >> okay. first of all, here's trump. okay. he's the biggest one and he's the most beautiful. >> reporter: scaramucci said eallident 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? : maason: major garrett at the white house. igank you, major. one of the biggest issues facing scaramucci is the russia investigation. the president has been critical of the special counsel and has firpower to fire him, but so far mr. trump is just firing at gom. here's julianna goldman. >> reporter: even with president t ump'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

teks. >> i can say that the people that have been hired are all hillary clinton supporters. >> reporter: mueller's first hur hires, one worked for the fointon foundation, all four donated to the democrats. >> people should know what plks' pasts and their motivations and their political motivations. >> 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 reontier for president trump, but it's a method he's employed repeatedly over the course of res business career. last year, mr. trump called the woman who accused him of sexual assault "sick" and "horrible." in a 2007 deposition, 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 5,itical of the defunct program. but now the stakes couldn't be higher, and he's trying to t scredit the special counsel. difellow republican who was praised by none other than newt gingrich, who tweeted that mueller's reputation "is impeccable for honesty and integrity." attorney general jeff sessions discussed campaign related issues with russia's ambassador contradicting his public statements. a spokesman says he had no >>nversations with russians about any campaign or election. anthony. >> >> mason: julianna goldman, thanks. members of congress have a message for the president: don't antagonize the special counsel. you could regret it. here's chief congressional hirrespondent nancy cordes. st it would prompt a fire storm. >> reporter: members of both e waies 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 licaul 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 hill,eep 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. >> reporter: iowa's chuck grassley says sessions was right to recuse himself. genera attorney general can't be a wing man for a president.

he's got 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. 's 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 f. conducts himself. he doesn't wake up in the morning and read those things and have it impact his ability is do his job. he's going to do his job. >> reporter: some republican prdes praised the new choice for white house communications director today, emphasizing his poise and charisma. but others complained to us that he has no experience with communications strategy or planning, something that 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 urn e the nation." john, as nancy pointed out, or oft mueller enjoys an oncellent 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 then you get mmediate validation of mueller's work by republicans. so if the president wants to say ch's a witch-hunt, then you have anrco rubio and paul rya you blow, republican voices saying it's not, they trust him, it's errt of... it reenergizes the legitimacy of the work that mueller is doing. ten the president went after .brmer f.b.i. director james comey and said a number of ritily critical things, saying he lied, it was interesting that very few republicans followed him along in that. and so it puts the president out on an island. and this is a way in which anthony scaramucci's job will be a challenge. ha that these comments the president made to the "new york e "ns," they help preserve the elesident perhaps in terms of perhap to weaken anybody who tauld attack him, but it absolutely gets in the way of dae president's agenda, the things he wants to do for the people who elected him. because the stories are a distraction and they... s hablicans 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 t e president to perform in a aty that the collective group at the white house, that the team wants him to kind of stay on agssage, stay in the strategy. o 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, and that can e dermine the rest of the operation and in a place where oderybody can go see the soesident, they sometimes worry about people doing things behind their back. >> mason: john dickerson, thanks. and john's guests on "face the nation" this sunday include

adngressman adam schiff, the top democrat on the house intelligence committee, and republican senator susan collins of maine. in the middle east, at least six odople were killed today in clashes between palestinians and israelis. anger boiled over when the veraeli government tightened security at one of jerusalem's holiest sites. jonathan vigliotti is following this. ptedeporter: 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. -- mnew measures-- metal detectors and hundreds more police-- were added after two israeli policemen were shot dead last week. tensions turned deadly today.

two palestinian teenagers were d ot and killed in jerusalem, and a third man was killed in dse west bank. hundreds were injured and more than two dozen arrested. five israeli security forces were wounded. palestinians have long accused israel of trying to 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. t're's dr. jon lapook. >> reporter: it's the most comprehensive 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. .nd in later life, manage depression, diabetes, smoking, and loneliness. d . richard isaacson is director of the alzheimer's prevention ill ic at weill cornell medicine at new york-presbyterian. t alzheimer's starts in the yain 20 to 30 years before the first symptom of memory loss. and that leaves ample time to make a brain-healthy choice, or to intervene in some way. >> reporter: one patient is jack leabaum, who is fighting the ervenestages of dementia with lifestyle changes and the occasional joke. es any dreams? >> i had a crazy dreams last night. i dreamt i was a muffler and i mke up exhausted. >> reporter: but he also counsels 36-year-old isaac brody, whose family history concerns him. >> my grandfather passed away tiom dementia. >> reporter: is it in the back of your head, "this is something that i really want to avoid?" >> you know, i'm 35, 36, you start having kids, like, you just want to now just be healthier, and just, like you know, be feeling good.

>> it's time. 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 the growing evidence that what you do today omn 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. eds. 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.

way, it will only take 29 minutes to commute between new york and washington one day, traveling on something like an ultrafast underground train. foun, the founder of tesla and space-x tweeted yesterday he just received verbal government approval to build a hyperloop tunnel connecting manhattan, philadelphia, baltimore, and d.c. adie tomer is an urban planner and transportation expert. >> elon musk is a modern day, infrastructure p.t. barnum, and it's a testament that we're even talking about this idea today that is really decades away. >> reporter: maybe, but several enmpanies are already working to make the hyperloop a reality. one completed a special test on >>special track built in the nevada desert. nn 2013, musk dreamed up the idea of a hyperloop where passengers travel in pods that levitate and glide in a vacuum- ooaled tube with almost no aerodynamic drag. 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

flerica's fastest passenger train tops out at 150. ts it gets built, it would be a game changer. w all of a sudden folks who maybe have family and friends in washington can actually work in philadelphia and new york on a daily basis. hyperloop is capturing our imaginations because the thought of moving at such rapid speeds is nothing short of exciting. >> reporter: now hyperloop would still require federal, state, and local approvals and the cost would likely be staggering, in the tens of billions of dollars. 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. of commute. kris van cleave, thanks. ...how s 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.
