Local media reports that people heard shots fired and they published a photo online of the truck apparently riddled by bullet holes. President hollande returned from a Cabinet Meeting to nice now. The Prime Minister will meet with local officials and police to be updated on the situation. Pelley and well have extensive coverage from nice on cbs this morning. Elaine cobbe, thanks. Because of the attack in france, donald trump says he is putting off the introduction tomorrow of his running mate indiana governor mike pence. His selection comes as our cbs news poll shows the race tightening to a 40 40 trumpclinton tie. Trump has taken a 12point lead among independents but most voters find both candidates untrurs clinton has a fivepoint lead in that category. Few voters know anything about mike pence. So heres Major Garrett to change that. Reporter scott, governor pence landed at a private airport in new jersey a short time ago and is headed, were told, by two sources familiar with the matter to a dinner meeting with donald trump to discuss strategy and staffing for the upcoming campaign, thus continuing conversations that rounded out the republican ticket. I support donald trump. I mean, hes got the right vision for this country. Reporter donald trump spoke with mike pence last night and again today as he settled on the indiana governor to bring staunch conservatism and a low key personality to the ticket. The 57yearold pence was born in columbus, indiana, and has a law degree from indiana university. He served six terms in congress and carved out a record of social and economic conservatism that Tea Party Republicans fancied long before they became a force within the g. O. P. Pence initially endorsed texas senator ted cruz in the indiana primary that clinched trumps status as the presumptive nominee. I see ted cruz as a principled conservative who has dedicated his career to advocating the reagan agenda. Reporter and earlier in the campaign, pence publicly opposed trump on two big issues, temporarily banning muslim immigration and a new trade deal in asia called the transpacific partnership. But pence came around to team trump and has been singing his praises since he laid claim to the nomination. Hes a builder. Hes a fighter. And hes a patriot. Reporter a new cbs news poll shows 86 of voters are undecided or do not know enough about pence to form an opinion. Pence has not been touched by scandal as a member of congress or as governor, but he did come under fire for a bill that allowed businesses to deny Services Based on their religious beliefs. After swift opposition around the country, pence had the law redrafted. Its been a tough week here in the hoosier state. Reacting to a horrible attack in france, trump stayed he is postponing the unveiling of his running mate. Trump said on twitter, when will we learn . Scott, he also said, it is only getting worse. Pelley Major Garrett, pelley Major Garrett, thanks. John dickerson, our cbs news political director and the anchor of face the nation is in our Cleveland Convention newsroom this evening. John, what does mike pence bring to the ticket . Well, he is not of washington, but he has some washington experience. And donald trump said he wanted to pick somebody who could help him actually get something done in washington. He has strong ties to the social conservative part of the republican party, so he helps trump cinch up that unity, which is part of what hes trying to do here at the convention, and also unlike somebody like newt gingrich, who is a bit of a rambunctious politician, mike pence is not somebody who will cause issues or probably not somebody who will cause issues for the person at the top of the ticket in terms of behavior and staying on message. Pelley in our poll today the vast majority of republicans said they believe their party is divided. How does pence help heal the breech . Reporter so in delegates i talked to here in cleveland about the possibility of his pick and the naming of him, what they like about pence is theyre worried that donald trump will be unpredictable, that he wont participate in the compulsory exercises of campaigning that show youre president ial, and what they see in the pence pick is a seriousness about governing. As one put it, he is a stabilizing pick, which means that donald trump has been the kind of the attack dog as a candidate, so he doesnt need an attack dog in a vice president. What the delegates here are saying is they like the fact that pence is a little bit more even keeled, and that might add balance to the ticket so they can compete in the fall. Pelley sort of a role reversal from usual politics. John dickerson in cleveland for us, thank you very much. Some of the most important business of the Republican Convention is unfolding right now. The people who make the rules are hearing from dissidents who want to derail trumps expected first ballot nomination. Julianna goldman is in cleveland. Obviously we did not stand adjourned for three hours because of a jammed copier. Reporter in cleveland today, a printer problem became code for a lastminute effort to prevent a messy nomination fight on the Convention Floor next week. While delegates met in one room, r. N. C. Officials and Donald Trumps aides huddled behind closed doors with conservative activists and leaders of the stop Trump Movement. Sean spicer is with the r. N. C. I think what we want to do is make sure we have the greatest amount of unity coming out of this convention. Reporter antitrump forces have been waiting for the rules meeting to try to unbind delegates from having to vote for trump on the first ballot, but today r. N. C. Officials told cbs news theyre confident they dont have the votes to prevail. One question mark whether the stop Trump Movement will still get the 28 votes needed to force a minority report, which could create a stir on the Convention Floor, airing g. O. P. Infighting for all the cameras to see. The conventions longawaited list of speakers did highlight the g. O. P. Divide. Glaringly absent are many party leaders, like 2008 nominee senator john mccain, who said he prefers the grand canyon to cleveland. Why are you skipping the Republican Convention . Because im campaigning for reelection. Reporter 2012 nominee mitt romney wont be here, nor will either of the former president s bush. I havent begun to start working on my speech yet. Reporter those that will be speaking include House Speaker paul ryan and Senate Majority leader mitch mcconnell, both of whom have on occasion criticized trump. The stop Trump Movement likely faces its biggest test tomorrow when the rules Committee Meets for a second day, but, scott, we spoke with many of the delegates here, and even those who are bound to other candidates say the cake is baked and its time to rally around trump. Pelley Julianna Goldman in cleveland for us. Julianna, thank you. Well, when our poll asked voters who would do a better job on the economy, trump beat clinton by 11 points. Last month they were dead even. Tough times are drawing voters to trump as don dahler found out in johnstown, pennsylvania. Reporter there was a time when johnstown, pennsylvania, led the nation in steel production. That industry and its thousands of goodpaying jobs have long since left. This is a small town. It used to be kind of like a small pittsburgh. And its just. Its just a hardhit area. Reporter welder john silk works at one of the last remaining factories. His faith in the future has been shaken. You were a lifelong democrat. Yes. Reporter and youre wearing a trump shirt. How did that happen . If he does half of what he says hes going to do, its a boost in the right direction. You can only go forward with him. I dont think you can go backwards, and you sure as heck cant stay the same. Reporter youve lost faith with the Democratic Party . Yes, absolutely. Reporter another resident, peter ankney, registered republican for the first time in his life and also plans to vote trump. We have way too many government regulations. Donald trump talks about undoing them, getting them out of the way, and letting our local industries do what they do best and just create jobs. Reporter but restoring johnstowns former glory is a tough order. The average income here is less than half the national average, and 34 now live in poverty. Our economy is obviously not recovered from, you know, the crisis in 2008, so we got to start worrying about home. Weve got to take care of this place first. Reporter pennsylvania has favored democrats in every president ial election since 1992, but this year the ghosts of longdead industries could have their final revenge. Don dahler, cbs news, johnstown, pennsylvania. Pelley well, Hillary Clinton will accept the democratic nomination two weeks from tonight. What will her ticket look like . Heres nancy cordes. Are we ready for hillary . [cheering and applause] reporter clinton held her own v. P. Tryout today for virginia senator tim kaine in his home state. Do you want a youre fired president or a youre hired president . Reporter kaines resume have propelled him on the clintons short list. Hes the former governor of a battleground state, a member of the Senate Armed Services committee and he speaks fluent spanish. [speaking spanish] still, he faces stiff competition from some of his senate colleagues, all of whom met with clinton at the capitol today. The tightlipped bunch included ohios sherrod brown. Good meeting, good meeting. Reporter Elizabeth Warren of massachusetts, new jerseys cory booker and vermonts bernie sanders, who got a standing ovation in the closeddoor meeting after endorsing clinton earlier this week. She will be the next president of the united states. Reporter clinton has campaigned with the others, too, but the timing of todays event is intriguing. It is her last big public appearance before she gets overshadowed by trumps v. P. Announcement tomorrow and the Republican Convention next week. Now, next week in cleveland, they will nominate someone who thinks latino outreach is tweeting a picture of a taco bowl. Reporter senator kaine has described himself as boring, but that could be a plus in the eyes of the clinton campaign, which wont have to worry as much if hes the v. P. That he will upstage the person at the top of the ticket, scott. Pelley nancy cordes for us. Nancy, thank you. Well, she didnt apologize or take her words back, but today Supreme CourtJustice Ruth Bader ginsburg said she regrets making critical remarks about donald trump. In a statement she said her remarks were illadvised and judges should avoid commenting on a candidate for public office. Today mourners packed one of minnesotas largest churches for the funeral of philando castile. A Police Officer shot and killed castile last week after stopping him for a broken taillight. His death was one of the motivations for the Dallas Police murders last week. Anna werner is in st. Paul. [bell tolls] reporter a white horsedrawn carriage led the procession carrying Philando Castiles casket. Mourners packed shoulder to shoulder into the 3,000seat cathedral, but Church Officials said they wanted to support a hurting community at the request of castiles mother valerie. He is a king and i thought that would be the only thing suitable for him was royalty. Thats why i chose this place. Please, officer, dont tell me that you just did this to him. Reporter the video of castiles shooting by an officer of the st. Anthonys police department, streamed live by his fianceee on facebook, called national outrage. Castile had a gun in the car and a permit to carry. The family says castile was the victim of racial profiling. The familys pastor reverend steve daniels, jr. , agreed but asked mourners to come together. Were not each others enemy, so i hope that this childs death will be that seed that will produce us coming together.
