>> reporter: donald trump tonight didn't even mention the endorsement. >> so saturday, go out and vote. >> reporter: governor haley, who has an 81% approval among south carolina republicans, has been sounding the alarm on trump for months. just yesterday, saying trump was out of line to knock president bush over his handling of 9/11. >> it's unfortunate. i took my daughter to her first debate on saturday, and i mean, i was embarrassed to see a candidate criticize a president on one of the worst days that and criticize how this president handled it. >> reporter: all south carolina's key republicans players, now lining up against trump. haley and senator tim scott with rubio. senator lindsey graham in jeb bush's camp. today, trashing the billionaire. >> i think he's crazy. i think he's unfit for office. >> reporter: trump says graham's the crazy one.

this could set a dangerous precedent. and just a short time ago, the justice department releasing a statement, saying, quote, it is unfortunate that apple continues to refuse to assist the department. abc's senior justice correspondent pierre thomas tonight on both sides. >> reporter: tonight, the fbi and apple in a titanic clash between personal privacy and national security. >> shots fired. >> reporter: since the bloody end of the san bernadino attack, the deadliest since 9/11, the fbi has been helplessly staring at syed farook's cell phone, an iphone a-c like this one. >> we still have one of those killer's phones that we have not been able to open. it's been over two months now. >> reporter: and tonight, a federal judge is now siding with the fbi, ordering apple to find a way to hack into the iphone used by farook. tonight, apple is refusing, saying if they break into this phone it will set up a dangerous slippery slope. >> if you design a backdoor for one phone, you have to design it

the phone may hold critical clues about who farook was communicating with and where he and his wife, tashfeen malik, may have traveled. the problem? they don't have farook's four-digit password. the fbi believes that farook used apple's security option, bascially a self-destruct mechanism that erases all data if the proper code isn't entered after ten tries. bull with 10,000 unique possibilities, the fbi knows cracking the code is nearly impossible in just ten tries, and so it wants apple engineers to design software to break into the phone. in an impassioned state, ceo tim cook said, the government is asking apple to hack its own users. adding that the software is, quote, something we simply do not have, and something we consider too dangerous to create. cook expressing those same concerns recently on "60 minutes." >> there have been people that suggest we should have a bookdoor, but the reality is, if you put a backdoor in, that

guys and bad guys. >> it's not about us getting a backdoor. i want want a door, a one doe. i would like people to comply with court orders. >> reporter: president candidates weighed in today. >> who do they think they are? >> reporter: but apple is standing firm tonight, arguing if they found a way to break into that phone, they'll be able to break into any phone which could put the private data of millions of users at stake. >> and bee yarp thomas with us live from the fbi tonight. and pierre, you told us, this battle could effect far more than just the san bernardino case? >> reporter: that's right, david. manhattan's chief prosecutor told us he alone is trying to open more than 150 encrypted i phones in cases ranging from murder to sex crimes and robbery. it's an epic legal battle that could go all the way to the supreme court. david? >> all right, pierre thomas with us live tonight. pierre, thank you. now, to pope francis this evening, and his historic visit to mexico. these images coming in just moments ago here of the pope at

crowds gathered. that visit to the mexico/u.s. border, making headlines in the presidential race here in this country. donald trump saying the pope does not understand the danger of an open border. abc's chief foreign correspondent terry moran with the pope, plus, the moment pope francis was visibly upset with crowds, pulling him toward them. >> reporter: he stood on the banks of the rio grande here at this troubled border. across the river, a few feet away in the united states, americans, including some undocumented immigrants, praying with francis, remembering the thousands who have died in the desert, trying to get to the u.s. spiritually, there was no border here today. joy was crowds on both sides. a hugely symbolic celebration. a message from the pope. this week, donald trump sent a message back, in an interview with fox business. >> the pope is a very political person. i don't think he understands the

we have with mexico. >> reporter: but mexico has embraced this pope. at one point yesterday, mobbing him, almost toppling him until he rebuked them. "don't be selfish," he said. and at every step, francis has spoken out, blasting some businesses and slave drivers that exploit employees. and especially taking on the violence of the drug trade here in this city, once racked by thousands of murders. but now, juarez with crime down to manageable levels, proudly hosting the pope. for francis, this isn't about politics. it's about taking in a stranger and welcoming in the refugee. he would say, that's christianity. david? >> terry moran with us tonight from mexico. terry, thank you. and overseas tonight, and to a deadly terror attack in turkey. at least 28 people killed in a car bomb explosion, in that country's capital. the blast apparently targeting inging turkish military buses. turkish officials calling the attack well planned. no one claiming responsibility so far.
