all as a consequence of the scott walker and rick perry withdrawals. tomorrow is a critical day. it's the end of the third quarter fund raising period. the third quarter, the last three months is when every single candidate, every single campaign tries to put as much money in the bank and keep it there so they can have gas money for the campaign buses but advertising money. when those reports start to come out we're going to see some candidates looking much stronger and some looking weaker. >>> coming up, high school quarterback walks off the field after a hard hit but ends up dying. it wasn't because of the head injury. what every parent needs to know about how that young man died. >>> just how safe is the car that you're driving now. volkswagen coming out with a fix for the millions of cars caught up in the emissions scandal. we're hearing of another potential auto recall. stick around. where our next arrival is... red carpet whoa! toenail fungus!? fight it! with jublia. jublia is a prescription medicine used to treat toenail fungus. use jublia as instructed by your doctor. are

he says i'm not chief strategist as he did in the interview he is specifically referring to scott walker and rick perry, candidates who got involved in day-to-day process and tactics instead of coming forth with leadership and ideas. christie is concentrating what he wants to do for the country the meantime there is a major scramble going on behind the scenes working exactly that process of raising cash. jenna. jenna: important point to pay attention today and every day. carl, thank you. jon: the controversy over planned parenthood is taking center stage right now on capitol hill. the organization's president is testifying as a house committee holds a hearing on the taxpayer money that planned parenthood receives. peter doocy live in washington with more what is going on there. peter. >> reporter: jon, right out of the gate republican members tried to offer solutions. basically they don't have a problem with federal money going towards women's health. they don't want it going to planned parenthood who they describe as spending a lot of money doing things they shouldn't be doing. >> take the money

the supporters say they think he has a better shot now that two other governors, scott walker and rick perry have dropped out. carl cameron has the latest news from des moines. who are the latest donors trying to get chris christie back in the race? >> well, christie hasn't actually been out in iowa. he's come here about eight times, more than some of the candidates. but he's very far back in the polls. it's beginning to get towards crunch time here, shep. pretty soon, we'll be talking about money, like in about 24 hours, 36 hours from now. and what's happened today with these six donors, these six very, very important, influential republican activists in iowa are really the inside crowd with the five-term republican governor here. in this state. the governors have the caucuses next year. they have joined on with christie. coming as it does in the vacuum of the walker withdrawal last week and perry a couple of weeks before that, there is an idea for a lot of other candidates. bobby jindal has been here a lot and continues to think he has an opening with what would have been the walker

the red ants, not only do they not do anything about it, florida governor rick scott refuses to do anythingout it. even though miami is flooded or in war every year. so i don't have an answer of how you make this happen. because i think to an extent better messaging matters, but you have such a highly funded corporate campaign to ensure nobody knows science is complicated and put in people's mind. people don't have the time to follow the details of climate science. it is very easy to ignore or be confused about it. it's a really hard question. >> it's interesting because one of the things and i joke about you being optimistic but i kind of think when what we hear about climate change we turn it off. the fact you give us this series away to move forward. it makes it easier to accept that this is horrifying but we can do something about it. when i saw just drink more wine. i joke with you about being optimistic, but i want you to talk about that. >> the conservative corporate lobby has been very successful at one thing and they do so in a number of ways. some of it out right lying, but also t

the parenthood hadn't done any of these horrible things they were accused of, florida governor rick scottok that result out of the investigator's report and wrote up his own results which were more to his liking. in state after state after state they keep finding despite all the considerable anti-be plan the parenthood activism by republicans right now and these screaming allegations from anti-abortion groups this year, this he keep finding over and over and over again in blue states and red states, this keep finding planned parenthood isn't doing anything wrong. this is the health care provider of choice for millions of american women. the most recent polling on the subject of planned parenthood shows that americans have a higher who opinion of planned parenthood than, well, than any other person or political entity that nbc or the "wall street journal" could think to poll on. look at this from the latest nbc poll that came out this weekend. donald trump was the most disliked, a net 33% net approval rating. republican party was the second worse off, are 16%, jeb bush was the third worst

seems to be accelerating because of the departure of scott walker and rick perry before him. chris christie and a number of candidates see real opportunity. christie calm here today to get the endorsement of suction major iowa influence peddlers in the g.o.p. folks who really comprise the inner circle of governor terry branstad the five term republican governor of iowa who has the best by far organization in the first caucus states. these six insiders from branstad's camp provide money, organization, ground troops, precisely what's necessary to win the iowa caucuses. for christie it's an opportunity to show off supporters in what is perceived as some degree of vacuum in the absence of walker and perry for these candidates. kasich is here. there are a number of one withs equally. bobby jindal, marco rubio is coming here. a number of candidates see this as an opportunity. tomorrow is a very, very important day on the campaign trail because it is the end of the third quarter. the fundraising in the third quarter of the year that precedes a presidential election is the three mont

. >>> what would you do specifically that you did as governor, you can argue rick scott as governor thatas president. >> reforming our tax code is maybe the highest priority. it is going to be hard to do because there's a lot of entrenched interests, lowering rates, lowering as many deductions as possible. >> jeb bush promised me then, we were in lineup for a republican event, he would release a plan to simplify the tax code, to encourage investment, to renew that $19 billion revenue turnaround he saw in florida in eight years as governor there. he did just that today but kind of fell on deaf ears because of all of the shenanigans and heated debate back and forth outside the capitol on this iran deal. trying to understand all of this, mark hanna says for republicans it is not helping them. mark, your fear or happy hope is that republicans are just falling on the donald trump -- >> this is one of the big policy ideas of the republican primary. right now, nobody is paying attention. everybody is paying attention to what donald trump was saying. >> or hillary clinton, and whether she goes t

not insignificant that two of the candidates now, rick per rained scott walker, were both on the right end of the republican party. and he didn't seem sure footed on national issues. he switched his stance on immigration, for example. there are other issues where he seemed to adjust. i think there were some governors, reagan and bill clinton being the obvious, who are really tuned into national issues. i think it took scott walker more time than was good for him in the end to really get locked in on those issues. i have heard that from conservatives who have talked to him, who were trying to advise him. so, i think it's the money, but the money is both the cause and a symptom of another problem. >> the cause and the symptom, susan del percio, we have the money. we have the polls. does one plus one equal three here? and he getting a call perhaps from a big funder, perhaps the koch brothers, we don't know, and then he reacts, his campaign staff says it's time to move on, you put those two together and it looks a little bit too insur mountable? >> he actually didn't need to get the call f

i'm sitting here in a state where the most unpopular governor in the country, rick scott, who you can'tne who says they are a fan of just got re-elected. i think what the clinton would tell you, no matter what her favorables look like she is in a commanding position versus the other democratic candidates. she remains in a commanding position. when you look at democrats and their attitude toward the e-mails those stories haven't hurt her among her core base. i think hillary's biggest problem is the e-mail issue is playing out in a congressional committee, controlled by the opposition party that is determined to keep drip, drip, dripping out information about it and it's something that is getting traction in the press. she cannot get away from it. i think it will draw down her favorables. i don't know if it changes her position in the race, at least not right now. >> we go back to this very pressure report about bryan pagliano intend ing to plead the fifth amendment when asked to testify before the benghazi committee. it is hard to figure out what he would fear a self incrimination about.

folks who -- refuse to stake a stand include scott walker and rick perry.s where they stand at least today. sometimes that does change. note that all declared democratic candidates have said that they are in favor of birth right citizenship. >> okay so melissa this policy has been around for more than 100 years, why now? >> you know at the debate, the recent republican debate, donald trump said something like you wouldn't even be talking about immigration if it weren't for me. is on this issue, of birthright citizenship, that's true. he is forcing presidential candidates to talk about it. but, efforts to end birthright citizenship go back to at least 1993. that first attempt in 'ed 3 came from a democrat. -- '93 came from a democrat, senator reid after nevada. the current leader of the democrats in the senate. he proposed a bill to end birthright citizenship and here's him talking about that bill back in 1993. >> how about offering a reward for being an illegal immigrant? no -- no sane county would do that. right? guess again. if you break our laws by enter

but floridians, not only do they not do anything about it, but florida governor rick scott refuses tohing about it, denying that it exists. even though miami is getting flooded more and more every year. >> yeah. >> and so i don't have a good answer of how you make this happen. i mean, you just, you know, because -- you know, i think that, yes, to an extent better messaging about this matters, but you have such a highly funded corporate campaign to insure that nobody knows. science is complicated, it's easy to put doubt in people's minds. people don't have the time to follow the details of climate change. they have soccer practice for their kids. it's very easy to be confused about it, and exxonmobil does a heck of a job making that happen. it's a really hard question. >> it's interesting, because i also think one of the things -- and i joked about you being very on themyic, but i -- optimistic, but i kind of hear when we think what we hear about climate change is just doom, we turn it off. but the fact that you give us here is a way to challenge this, here is a way to move forward, th

for him to attack anyone's appearance when he looks like he has a squirrel on his head. >> rick perry's out. scottker has dropped from first place in the quinnipiac poll in iowa to tenth place in the poll out today. scott walker is falling off the map. donald trump winning there and everywhere else. donald trump's campaign said they have given out 20,000 tickets for a donald trump speech in dallas on monday. bobby jindal really did just tell cbs that donald trump shouldn't make fun of carly fiorina's appearance since he looks like a squirrel is sitting on his head. the republican race for president this year is so nutty and swerving so unpredictably right now if it were a car and you were a cop you would pull it over and breathalyze it. on the democratic side that race starting to weave in and out of its lanes. i can give you hot off the presses polling from the brand new msnbc marist poll, one interesting new angle on what's going on among the democrats. this full poll is not going to come out until next week. we have an advance look at the matchups they polled on for hillary clinton and joe bide

let's begin with katherine scott on the benjamin franklin parkway. >> reporter: hi, rick, this time yesterday the parkway looked different it was packed with people, now it's cleanup time. they have made a lot of progress, there's work left to do. the cross street of the parkway is open, there's lots of equipment and vehicles they are breaking down, quite a bit of stuff all the fences and structures, all the infrastructure to clean up after yesterday's papal mass. cleaning up after hundreds of thousands of people is not easy feat. crews are out today trying to restore the parkway to it's prepope appearance. >> i'm honestly really impressed how fast they are cleaning things up. >> i thought it would be worse than it is. i didn't think i would be able to walk through the streets. >> reporter: streets department vehicles are clearing away the trash and the debris the crowds left behind. while many roads are reopening, much of the parkway is closed including eakens oval while crews breakdown equipment to pack it away. for some getting to work wasn't easy. pallets of water sat in piles on the park

scott walker's. decision. he becomes the second, rick perry a week or so ago. we will look for your comments on twitter, you can send us a tweet at c-span. scott walker stepping down from the race. he becomes the second republican to do so, as i mentioned, rick perry a week ago. the journal sentinel in part of their article say that now walker joins rick perry as one of the first presidential candidates to drop out of one of the most robust report can field in years. walker is withdrawing before several other lives here longshots such as bobby jindal, lindsey graham, and former new york governor. tweets about the reaction, quotes lindsey graham, i think trump has taken a lot of oxygen out of the room, but i'll all i can say with a lot of people in a race it's hard. let's go to shawn, and maryvale, tennessee. >> good news. one less for public and on the field. he had terrible ideas, we see have -- what he has sent to a state. -- the state. no new ideas coming from the right. it is a party of progressives -- regressives. i wish they would bring bernie sanders into

rick. and scott walker. said tens ofac millions of dollars when they themselves are not of money. blocking and tackling of a campaign still needs to exist. raise hardate can dollar money and have enough the function, they will have the money to function for a long time. that might make the campaign go longer. points me to me is that donors do not really like eighth place finishes in iowa or ninth place finishes in new hampshire. so those checks may start to try out. an issue. i want to convey one thing. i have been e-mailing back and inth with a lawmaker who was the room when boehner told the conference this and some remarks coming out as lawmakers are walking out. paul ryan just told reporters he does not want this job. anything can happen. abouters just finding out this now. paul ryan has made clear, leadership is not a place he wants to be, particularly if he sees a way forward on tax reform. he is telling reporters now that he does not want the job as figure of the house. that takes out a key candidate. to a lawmaker who just e-mailed me, given caller from boehner, it was an e

nothing to say that scott walker couldn't come back and stage a successful stand in iowa. >> except he was running out of money very quickly as supporters were abandoning him. we have rickee-term governor of texas. he dropped out first. now scott walker, two-term governor of wisconsin, he drops out. i suspect more governors, current and former will probably be next, outsiders, those never elected will do incredibly well. why? >> well, there is no stronger force in american politics than the outsider dynamic and carly fiorina is the beneficiary of performances and that's - reflected in the host most recent polls but with more buzz is more scrutiny and she has to prepare for attacks on her business record. this is what the devil mitt romney in the last election and sometimes what is thought to be smart and successful in the world of business doesn't always translate into the the world of politics. so she needs to get ready for those attacks. i thought when barbara boxer used those business attacks against her in 2010 they were very affected. having been through that, i think carly fiorina has all her ducks in a row and will be able to respond when those attacks come. >> t

but scott walker at 5% in iowa means in that state he's ahead of jim gilmore, lindsey graham, bobby jindal, also rand paul, rick santorum, chris christie. i mean, scott walker had more support in iowa than any of those other guys, and he has just quit the race for his lack of support. how long can the rest of those guys stay alive? if scott walker's out, who's next? joining us now is wisconsin state senator john erpenbach, who has a long history of battling with scott walker in his home state of wisconsin. senator, great to see you. >> thank you, rachel. >> when scott walker said today he was suspending his campaign, i don't know who it was. but somebody in the room applauded like a seal being commanded to perform. i wonder if that was sort of a weird audiovisual metaphor for how this is being greeted by governor walker's old opponents at home in ws which is. are you happy to see him out of the race? >> yes, i actually am. but it's kind of a double-edged sword. he's obviously going to be back here as governor in the state of wisconsin. but he didn't have to give up his seat to go run for president. i'm surprise

. >> trump will go through the list of people, name by name, he talks about rick perry and scott walkersays look what happens when people come after me, they plummet in the polls. but it doesn't seem like it's play iing out with rubio. >> rubio knows the trump act is getting old. that it's like when chris christie first told someone to sit down and shut up, everybody cheered. after the 50th time, it became boarish. that's what is happening with trump. it's becoming too much and it's masking a lack of substance on his part. trump launched his tax reform today and marco rubio got him to step on his story by calling him a lightweight. so he's succeeding. second, he's going after -- the poll shows bush has 7% of the vote right now. marco rubio wants that 7% and he wants jeb bush's donors and he's trying to show he can punch back the way jeb bush couldn't. >> let's look at the latest poll showing how tight things are. donald trump just one percentage point ahead of ben carson. so basically in a statistical tie. what do you make of those numbers? >> debates matter. before the cnn debate, dona
