Man, thats this mornings eyeopener is presented by toyota, lets go places. Welcome to cbs this morning as you wake up in the west, donald trump is meeting right now with House Speaker paul ryan. Trump flew into washington this morning on his 757. Ryan stopped for breakfast at burrito brothers, a Mexican Restaurant in the capital. The two are discussing significant policy differences that divide them. A week ago ryan announced hes not ready yet to support trump in november. Major garrett at the meeting site at the headquarters in washington. Good morning. Reporter good morning. Donald trump is inside Republican NationalCommittee Headquarters meeting with the Party ChairmanReince Priebus and House Speaker paul ryan. Hes drawn dozens of cameras, hundreds of reporters. And as you can hear, a large contingent of protesters calling trump among other things a racist and saying he and the Republican Party are now aligned. Its that rough Alliance Trump is going to have to work through and with his republican leaders. I think we want to see if we have the same ideas because i represent a large group of people with very strong ideas and foundations. Donald trump remained optimistic differences with House Speaker paul ryan can be dealt with. You can have differences. If you agree on 70 , thats a lot. Reporter finding 70 agreement will be a challenge. They want to cut your social security. Im not cutting your social security. You cannot tackle debt problem in america if you dont fix this entitlement problem. We have 11 Million People in the country that came in illegally. They have to go out. We have to come up with a solution that doesnt involve mass deportation. Donald trump is calling for a shutdown of muslims entering the united states. What was proposed yesterday is not what this party stands for. Trump stepped back from his temporary ban on muslim immigration and named former new york mayor Rudy Giuliani head of a commission to study it. We have exceptions. Again, its temporary. Ultimately, its my aim to have it lifted. Right now there is no ban. Congressman kissnzinger remas opposed. If he doesnt change his rhetoric, his beliefs, if he doesnt articulate them better, a lot of people will hold out. Trump took heat from mitt romney, it is disqualifying for trump to refuse to release his tax returns, adding the documents would rule out hidden inappropriate associations with foreignentities, corinth organizations or other unsavory groups. Trump insists voters dont care and wouldnt learn much. A tax return you learn very, very little. At the right time ill release them. I hope to release them. Trump claims he cannot release his tax returns because they are under active audit. The irs says there are no regulations that prevent a taxpayer from doing exactly that. Of course, theres some history between mitt romney and donald trump on this issue. Trump said romney was unwise not to immediately release his tax returns in 2012 and saying his failure to do so hurt him very badly. All right, major. Thank you very much. Mitt romney has an unlikely ally criticizing donald trump for withholding those income tax returns. Democratic candidate Hillary Clinton stepped up her attacks yesterday. Shes also suggesting he may have something to hide. Nancy cordes tracking the democratic race. Good morning. Reporter good morning. Clinton camp points out even notoriously secretive Richard Nixon released his returns prior to being audited. My husband and i have release 3rd 3 years of tax returns. Clinton waded into the tax flap in new jersey. Youve got to ask your self, why doesnt he want to release them. Yeah, well, were going to find out. Reporter the topic was a welcome diversion for clinton after a disappointing primary in virginia. Her campaign admits her rough patch probably isnt over, warning donors in a memo obtained by cbs news that, quote, a number of upcoming primary contests in may structurally favor Bernie Sanders but their outcomes will not change the trajectory of the primary. West virginia, thank you. Reporter to understand why, just look at west virginia. Sanders won the state by 15 points but got just 7 more pledge delegates than clinton and hes trailing by nearly 300 with just eight states left to vote. Weve been fighting an uphill battle from day one. Sanders got frustrated wednesday when asked if his long shot campaign is hurting clinton in her fight against trump. Please do not moan to me about Hillary Clintons problems. Im in this race to win. Were taking on the democratic establishment. But with the largest primary looming, the senators california state director has bankruptly stepped down. In a statement he said he left because the campaign, quote, started to ignore digital organizing and started focusing on tv ad buys which has led to a series of defeats. Tv ads and organizing have both been strengths for the sanders campaign, but a couple of weeks ago the staff was cut in half and the budget for advertising has shrunk, too, which has led, charlie, to tough decisions in this closing stretch. Thanks, nancy. Mark leibovich in washington, good morning. Hi, charlie, good to be here. Is this conflict at its core more about style or more about content. As far as democrats go. No, donald trump. Donald trump. Yes. I think its about both. This essentially this story will be driven by what paul ryan says at the end. I think paul ryan is obviously getting some pressure, especially from his caucus to come around and just support the presumptive nominee. At the same time, and we dont see this as clearly, hes getting a lot of pressure privately from prominent republicans, mitt romney among them, to hold firm because ryan is the last line of defense for actually the Never Trump Movement in so much as it ever existed at all. Mitt romney stepped up the heat yesterday saying Donald Trumps refusal to release any of his tax returns is disqualifying donald trump, would be breaking with four decades of precedent on this matter. Could this be very tough for him . I think it is. Mitt romney is serving what is a pretty precise purpose here. Hes taking the role of the conscience of the republican not so much establishment but republican path. Donald trump said most americans dont care about this. True to a appoint. Its arcane, tax returns are something that make peoples eyes glaze over. At the same time its a nagging issue. Its gone on for a long time. It muddled the straight ahead tone donald trump likes to assume. Medical records, what about medical records. Medical records also. I guess a few months ago he released that completely superlative statement from his doctor. Again, these are two kind of lingering spring issues you dont want them to bleed into the summer especially in an election like this. He announced a fundraising campaign. He spent a lot of time saying i dont need anybody elses money. Do you think supporters will care about this, mark . I think this is probably less of a big issue, just because people understand in a general election, were probably talking bought billions. Whether donald trump had that money or not, or would be willing to spend it or not, its the kind of thing most people would assume if you have one of two candidates youre going to round up as many supporters as you can. I dont think that will be a big issue but again takes away from the message. Cbs will bring full coverage of trumps meetings with the republican leadership. You can watch at cbs news.

A Massachusetts State Police spokesperson said simone had warrants for assault and battery with a dangerous weapon, larceny and failure to stop for police. Wasnt fighting him so a little bit much.
