We begin with that big meeting with donald trump coming facetoface with paul ryan this morning. The unity of the Republican Party possibly at stake. Abcs tom llamas is on capitol hill with the latest. Good morning, tom. Reporter robin, good morning to you. The meetings under way at the rnc headquarters. Trump inside and outside protesters you can hear and see them. Trumps most important metering is happening inside this building. Ryan trying to figure out how to make sure he can keep the party happy and also keep donald trump happy. This morning donald trump bringing his deal making to washington to convince Republican Leaders to get on the trump train. His pitch for unity simple. No matter what you have youre going to have differences. If you agree on 70 thats always a lot. Reporter trump hopes that works on House Speaker paul ryan who has yet to support the presumptive gop nominee. This election is too important to go into an election at half strength. That means we need a real unification of our party. Reporter trump, who threatened to bounce ryan as Convention Chair now with a charm offensive. Paul is a good person and i dont know him well. I think thats part of the meeting. We have to get to know he knew everybody else because theyre governors, senators. I am a businessman. Reporter a businessman who loves to brag about his billions. And now trumps critics want him to prove it by releasing his tax returns. When you run for president , especially when you become the nominee, that is kind of expected. So you got to ask yourself why doesnt he want to release them . Yeah, well, were going to find out. Reporter trump claims hes being audited. Mitt romney says so what posting on facebook thats not a valid or legal reason and that trump is possibly hiding a, quote, bombshell of unusual size. Trump says, only when the audit is over. The answer is hopefully before the election. I would like to release. Reporter though his taxes remain a mystery he is revealing new details about his pick for running mate.

And tomorrow they ill be in cleveland for face to face meetings with the rnc over the convention. Trump wants entertainment including a country western act. George. Okay, tom, thanks very much. Lets talk more with jon karl down in washington this morning and, jon, about this meeting first. Paul ryan, the speaker of the house making it clear, dont expect an endorsement immediately coming out of this meeting with donald trump. But what is he looking for today . Reporter well, hes made it Crystal Clear that he eventually wants to endorse donald trump. But it will take a long time to get there. So dont expect that to happen today. Look, ryan is under enormous pressure george from his fellow House Republicans to come out and to unify and endorse the partys presumptive nominee. One very Senior Member of the house leadership who is quite close to ryan told me that the concern here is that trump could decide to effectively run against the House Republicans to run against the house just as he is running against Hillary Clinton to run as a true outsider, really a Third Party Candidate who happens to have the republican endorsement. This member of the house leadership told me that would be a disaster. For House Republicans. They are so far apart on so many issues. They have to find some Common Ground. Reporter if you went into a lab and tried to design a politician that was most unlike paul ryan you probably would have come out with donald trump. They differ stylistically and on all the major policy issues from trade to immigration but they do need to find Common Ground at least in terms of the vision of what it means to be a republican. Right now they look like two different visions. On the tax return issue, up until now donald trump has calculated it would cause him more pain to release them than withhold them but the pressure is going to increase. Reporter the pressure will absolutely increase, george. He is not the conventional politician and has gotten away with a lot that others couldnt have but on this one he will be forced to release those tax returns, especially now that he has said that he would, every Major Party Nominee for the last half century has released at least the summary of those returns, almost all of them their full returns and he will be under pressure every day to do that in the general election. Yeah, going back to 1976. Jon karl, thanks very much. Now to the latest on the stabbing spree at a mall in massachusetts.

Overnight we learned the suspect may have made threats in the past before the attack in this mall. This as we learn so much more about two heroes. This morning, were now learning beloved 56yearold teacher george heath was eating dinner with his wife at bertuccis wood oven pizza in the galleria mall when Arthur Darosa came in stabbing a pregnant waitress. My husband grabbed him. I think he grabbed him around the waist area, i think, trying to keep him so his arm wouldnt go up to stab anybody else. Reporter heath was stabbed in the head as he tried to intervene. He did not survive. I lost a good man. I did. He was a great man. Reporter the waitress surviving but in serious condition this morning and then another hero, offduty deputy james creed stopped darosa with a single bullet. Darosa later died at the hospital.

Now to that new warning about the zika virus. An article in the Harvard Public Health review saying holding the 2016 games in rio could create a Public Health disaster and is now calling for them to move location or even be postponed. Abcs dr. Richard besser is here with more. So tell us a little more about this assessment. This is a piece by a canadian Public Health law area and gives five strong reasons why he thinks they should be moved. Rio is in the heart of the outbreak. Not in the periphery, the second, this strain of zika is worse than previous strains and causes those severe birth defects in babies. The increase in tourism is going to spread the virus. Half a billion people coming in and going back to their countries will spread it and shorten the time that Public Health officials have to create new ways to prevent this in those countries where it comes back and its irresponsible to hold the games. The u. S. , the Major League Baseball moved two baseball games out of puerto rico for this very reason to prevent the spread of disease. What do you think about this assessment . You know, as a Public Health person i know the last thing you want during an outbreak is a lot of people coming in because it will spread it faster. But i dont think the games are going to be moved or postponed. I think the focus needs to be on making sure pregnant women dont go and those who go use repellant. And protect themselves. A new report about symptoms for zika. If youve been to a place where zika is spreading they want people to be alert to what those symptoms are. The first is a rash, usually itchy, you can also have fever, joint pain and bloodshot eyes. If youve been to one of these places within the past two weeks and you get those symptoms go ahead and get tested. Quick reminder what we can do to prevent the spread. Yeah, you want to do it now before mosquito season. Repair your screens and gutters and get rid of Free Standing water around your home and stock up on repellant because when mosquito comes you want to use that protection. Thanks.
