>> ninan: good evening, i'm reena ninan. this is a western edition of the broadcast. exactly 13 months after donald trump announced he's running for president, trump was back in new york today, formally introducing his running mate. indiana governor mike pence is 57 years old, 13 years younger than trump, and a staunch conservative. he's serving his first term as governor after 12 years in congress. pence is an evangelical christian, married, three children. major garrett was there for the unveiling of the g.o.p. ticket. >> i'm here today to introduce the man who will be my partner in this campaign. >> reporter: yes, but donald trump took his sweet time to get to indiana governor mike pence. first came the headlines. the terror attack in nice, france, that postponed this announcement by a day: >> we've witnessed horror beyond belief. >> reporter: then the failed coup in turkey: >> it looks like they're resolving the difficulty, but we wish them well. >> reporter: then a bit on jobs: >> they have been taken away, like we're babies.

taken away. >> reporter: then trump used pence to tee up an attack on hillary clinton. >> mike pence is a man of honor, character and honesty. we know that. hillary clinton is the embodiment of corruption. >> reporter: at times, trump seemed to lose the point of the entire event. >> we're the law and order party. i said, don't go into iraq. i said, that brexit's going to happen. i dominated with evangelicals. we're going to get rid of that horrible johnson amendment. >> reporter: about eight minutes later... >> all right. back to mike pence. >> reporter: ...trump got back to the task at hand. >> governor pence balanced the budget. can you imagine a balanced budget? indiana enacted the largest k-12 education funding increase. in the state's history. governor pence enacted the largest income tax cut in the state's history. >> people who know me well, know i'm a pretty basic guy. >> reporter: pence, who endorsed

ted cruz in indiana's primary, heaped praise on trump. >> donald trump understands the frustrations and the hopes of the american people like no leader since ronald reagan. we're tired of having politicians in both parties in washington, d.c. tell us "we'll get to those problems tomorrow." >> reporter: and then threw partisan punches. >> hillary clinton must never become president of the united states of america. >> reporter: after the announcement, trump and pence sat for a joint interview that will air sunday on "60 minutes." >> what do you think about your running mate's campaign and the tone and the negativity of it? >> i think this is a good man who has been talking about the issues the american people care about. >> but name calling? >> reporter: pence said he agreed with trump's call to renew the now-banned interrogation tactic known as waterboarding. c.i.a. director john brennan said earlier this week, post-9/11 use of waterboarding produced credible and valuable intelligence, but brennan said he would not use the practice now, and reena, he said if he was ordered to do so, he would

resign. >> ninan: okay, major garrett, thank you. well, the scene is set for the republican national convention, which gavels to order on monday. the quicken loans arena will serve as the base for our convention coverage. julianna goldman is there. >> reporter: as the trump-pence ticket made its debut, construction crews were putting the final touches on the arena where donald trump will officially become the republican presidential nominee. political conventions tend to be choreographed down to the minute. but heading into this event, there are several unknowns. the top concern here, security. this morning, rain kept protests at a minimum, but organizers and law enforcement aren't taking chances. in the last 24 hours, the area around the quicken loans arena has turned into a security fortress. streets are closed and barriers block access. thousands of police and federal officials are here on high alert. another question, money. organizers had insisted there are no problems.

but this week's politico reported that the host committee sent a letter to billionaire g.o.p. donor sheldon adelson, asking for $6 million, saying negative publicity around trump has turned away millions of dollars in corporate sponsorship. on friday, the committee said the letter wasn't authorized and it mischaracterized certain donations. "the host committee has contacted the adelsons' staff to apologize for the inaccuracy," they wrote in a statement. "the efforts to raise funds for the r.n.c. are ongoing." and what about the stop-trump movement? they tried and failed this week to change the rules that could have denied trump the nomination on the convention floor. >> they killed the conscience clause but they didn't kill the movement. >> reporter: kendall unruh heads a group leading anti-trump efforts. she says those grass-roots delegates will still make their voices heard. >> and the very thing that the r.n.c. and trump were truly trying to stop, they have now guaranteed they will get. >> reporter: unruh said the mike pence pick may convince some

conservative delegates to support trump. but reena, she also predicted that pence will get more votes here on the floor for vice president than trump will get for president. >> ninan: julianna goldman, thank you. well, stay with cbs news for in- depth convention coverage. lesley stahl's full interview with donald trump and mike pence airs sunday night on "60 minutes." also sunday, john dickerson hosts "face the nation" from the quicken loans arena in cleveland. his guests include trump campaign manager, paul manafort; former house speaker newt gingrich and cleveland police chief, calvin williams. scott pelley will have a special edition of the "cbs weekend news" sunday evening from cleveland. our prime-time coverage begins on monday. there's celebrations in the streets of turkey after a violent attempt to overthrow the government. apparently it failed. more than 260 people were killed in fighting in the cities of ankara and istanbul. thousands have been detained, including military and judiciary officials. turkish authorities blame the attempted coup on a cleric in the united states. turkey is a key ally to the

united states, a nato partner. flights have been suspended from a major air base. holly williams is in istanbul. >> reporter: in taksim square, istanbul's symbolic heart, people chanted their support tonight for turkey's democratically-elected government. less than 24 hours earlier in the same place, ordinary citizens faced down members of the military trying to seize power. we spoke to a turkish businessman: >> i'm ready to die for my country, and for my leader. and for this i am here. for this i am here. if you can come, please come. >> reporter: the failed coup began around 10:00 p.m. when tanks rolled onto city streets. military jets flew low over istanbul and the turkish capital, ankara. a bomb rocked the parliament

building, and members of the armed forces took control of turkish state tv, declaring martial law. but then the turkish president, recep tayip erdogan, called another turkish tv station from his cell phone, urging people to take to the streets. crowds of people heeded his call, confronting the tanks and the troops, even as they opened fire. ( gunfire ) this internet video appears to show a helicopter gun ship targeting a crowd of protesters. shortly after that, the soldiers behind the coup began to surrender, abandoning their tanks and laying down their weapons. this young soldier appeared close to tears as he was lifted from his armored vehicle by a policeman. early this morning, president

erdogan flew back to istanbul and promised to punish those who, in his words, turned the people's guns against the people. the irony is that president erdogan is himself accused of chipping away at people's democratic rights. reena, this failed coup could provoke another crackdown and more restrictions on personal freedom here in turkey. >> ninan: all right, holly williams on the ground in turkey. isis now claims it influenced the driver of the truck that killed 84 people in nice, france, and left more than 200 others wounded. elizabeth palmer is in nice, where conflicting accounts are emerging about the truck driver. >> reporter: the city of nice today reopened the road that mohamed bouhlall turned into a killing field. but for those blindsided by the tragedy, life may never return to normal. maecha nadjim is one of the volunteers trying to locate presumed victims, still missing. >> avez-vous vu cette femme?

>> reporter: people are anxious to help. but this afternoon, no one had seen 42-year-old aldja bouzaouit. she'd been watching the fireworks on the beach that night, and her relatives wonder whether, in the panic somehow, she could have been pushed into the sea. so the family thinks she may even have drowned? "well," maecha says, "we can't rule anything out." two days after the attack, there are still 16 bodies unidentified. this morning, isis claimed credit for bouhlel's attack, calling him a soldier of the caliphate. but though he had a history of violence and petty crime, there were no signs he'd been radicalized. his father in tunisia told reporters, he had a history of mental illness. bouhlel lived alone in this apartment. he is estranged from his wife and kids, and had recently lost his job. police are now combing through his things to see whether his troubles had finally turned him very recently towards extremist propaganda.

for france, reeling from three major terrorist attacks in less than two years, the idea of unbalanced "lone wolves" is a nightmare. interior minister bernard cazeneuve said today that the country faced a threat from individuals who engage in extreme violence without combat experience, training, or access to conventional arms. but of course, in the wrong hands, anything can be a deadly weapon-- even a 17-ton truck. one of those still missing, reena, is 20-year-old nick leslie, a student at the university of california at berkeley. he was last seen running away from that truck on the night of the attack. >> ninan: family members still searching. elizabeth palmer, thank you. well, in addition to the missing student from berkeley, three students from berkeley were injured. a father and son from lakeway, texas, were killed in the attack. omar villafranca learned more about them today. omar? >> reporter: 11-year-old brodie

copeland was excited about going on a summer vacation before starting middle school. on thursday, the unthinkable happened. brodie and his father, 51-year- old sean copeland, were killed in nice, france. we talked to two of brodie's classmates, alexandra pena and jenay meissner, who say he was always making people smile. >> he always wanted to make people laugh and play games with you and stuff. and if you ever left out, he always wanted to help you and play with you. it was really cool. >> reporter: so he wanted everybody involved. >> mmm-hmm. >> reporter: what do you remember about being in plays with brodie? >> well, he always got a part in it. >> reporter: always? >> yeah. >> reporter: that's what everybody wants to get. >> right. he always-- >> reporter: was he good at being on stage? >> yeah. he made it seem like he wasn't on stage at all. >> reporter: the community will remember brodie and sean tomorrow evening at a candlelight prayer service. their bodies will be flown back to the u.s. some time next week. reena?

>> ninan: omar in texas. well, in fort worth, texas, police officers and navy personnel from around the country attended the funeral for dallas police officer patrick zamarripa. he was one of five police officers keilled earlier this month by a gunman who wanted revenge for recent fatal shootings of african americans by police. zamarripa served in the navy before joining the police force. a protest over police shootings turned violent last night in san francisco. several demonstrators were arrested after clashing with police. the demonstration in oakland briefly forced a freeway to shut down. saturday marked one year since a gunman killed four marines and a sailor at a recruiting station and reserve center in chattanooga, tennessee. a memorial was held in their honor. the navy is now placing armed sailors at all of it's 1,300 recruiting stations. well, coming up, a town where tough times have some voters changing sides and turning to trump.

>> ninan: a cbs news polls out this week showed donald trump 11 points ahead of hillary clinton. now, the question of who would do better on the economy? as don dahler found out in johnstown, pennsylvania, tough times are drawing voters to trump. >> reporter: there was a time when johnstown, pennsylvania led the nation in steel production. that industry and its thousands of good-paying jobs have long since left. >> this is a small town. it used to be kind of like a small pittsburgh, and it's just-- it's a hard hit area. >> reporter: welder john silk works at one of the last remaining factories. his faith in the future has been shaken. >> reporter: you were a life- long democrat? >> yes.

>> reporter: and you are wearing a trump t-shirt. how did that happen? >> if he does half of what he says he's going to do, it's a boost in the right direction. you can't-- can only go forward with him. i don't think you can go backwards; and you sure as heck can't stay the same. >> reporter: you've 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 industry do what they do best and create jobs. >> reporter: but restoring johnstown's 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 the crisis in 2008, so we got to start worrying about home. take care of this place first. >> reporter: pennsylvania has favored democrats in every presidential election since 1992. but this year, the ghosts of long-dead industries could have their final revenge.

don dahler, cbs news, johnstown, pennsylvania. >> ninan: well, still ahead, a medical update for the history books. was mary todd lincoln's well- known depression due in part to a physical cause? physical cause?

here's dr. jon lapook. >> reporter: history has not been kind to mary todd lincoln. wife of our 16th president, she was a tempestuous, unpredictable force, and her son eventually had her committed. >> madam president, if you please. >> reporter: sally field's 2012 portrayal showed a fierce and sharp-tongued first lady. >> you think i'm ignorant of what you're up to, because you haven't discussed this scheme with me as you ought to have done. when have i ever been so easily bamboozled? >> this white area here is not her dress, it's her skin. >> reporter: but dr. john sotos, a physician and medical historian, says the famously fiery first lady was not only misunderstood, but misdiagnosed. sotos puts forth a new theory about mary todd lincoln-- her erratic behavior was caused by a condition called pernicious anemia. >> that impairs the body's ability to absorb vitamin b-12 from food efficiently. as a result, they become b-12

deficient eventually and that causes lots of problems in almost every organ in the body. >> reporter: it was a fatal illness until treatment was discovered, decades after her death. the disease can lead to many of the symptoms exhibited by mary todd lincoln-- a sore mouth, pale skin, difficulty walking and psychiatric problems. it can also cause swelling. >> the puffiness is not in a way that would occur with just an accumulation of fat. >> reporter: today, the disease can be picked up on a simple blood test, and easily treated with b12 supplements. >> she had a sick brain and was doing the best she could, in a very complicated, relentlessly demanding environment. and i think, to have done as well as she did, with the kind of handicaps that she had, i think that deserves admiration. >> reporter: dr. jon lapook, cbs news, new york. >> ninan: well, up next, the smartphone game pokemon go is a summer craze. but players are running into real life trouble.
