That trailer there behind the bushes that is largely destroyed, we talk to a man who lived there.

He claims the republican frontrunner has not released his tax returns because they may contain a bombshell. Trump tweeted in response that taxes made romney, quote, look like a fool in 2012. He sarcastically called romney a tough guy. Major garrett in washington looked at the issue that may affect tonights Republican Debate in houston. Major, good morning. Reporter good morning. On the Republican Debate stage tonight in houston, mitt romney no, no, not in person, of course. But through this issue of tax returns that he lobbed at donald trump yesterday. Trump has dismissed romney through this campaign as a weak nominee who should have won in 2012. Trumps republican rivals at another texas forum last night, they sided with romney. They are not exotic but we will release them. Very glad to release tax returns. Nothing to hide. Not a problem. The nice thing i havent made enough money that my tax returns are not that interesting. Reporter donald trump closest rivals had no problem respond from a challenge to 2012 nominee mitt romney who had this to say about trumps tax returns. Frankly, i think we have good reason to believe that there is a bombshell in Donald Trumps taxes. Every time he is asked about his taxes, he dodges and delays and says, well, we are working on it. Reporter the tax issue tripped up romneys white house bid but trump said he feels no pressure to release his returns at all. My returns are extremely complex and ill make a determination at the right time. Im in no rush to do it. Nobody has been bringing it up except for mitt romney.

Clinton is making four stops in the state where democrats vote on saturday. Nancy cordes is in columbia, South Carolina, where clinton is also thinking about the gop frontrunner. Nancy, good morning. Reporter good morning. Thats right. Republicans are not the only ones who are starting to come to grips with the notion that trump could be the gop nominee. Yesterday, the Clinton Campaign sent out this fundraising appeal saying, everything is coming up trump. A message meant to scare their supporters into opening their wallets. When with you talk about the trumps of the world to divide us up. Reporter trump that united the democratic candidates, at least temporarily. I listen to the rhetoric on the republican side. I dont recognize my country. You know . Senator sanders and i have been trying to run a Campaign Based on issues. They run a Campaign Based on insults. Reporter clinton is camped out in South Carolina, protecting her large lead in the polls here. Hi. Reporter sanders headed west in search of Greener Pastures and he found them. Here in missouri reporter 7,000 people came to here him speak in kansas city. Almost 10,000 in tulsa. I look out add this crowd, i dont think there is any way we are going to lose on tuesday reporter the only other candidate drawing crowds this large is trump. But, so far, the enthusiasm has not translated into turnout, which is down on the democratic side since 2008 in the three contests held so far. And that is a problem for sanders, who says this all the time. Voter turnout is everything. Our job is to create a high voter turnout. If there is a large turnout, i think we will do very well. Reporter translation . Sanders needs his young supporters to hit the polls in record numbers and offset clintons advantage with older and more reliable advantage. In nevada she won by a full 50 points and won the caucus. You say you want to create the revolution that clinton couldnt. Is turnout a sign that that revolution isnt happening . Its a sign that barack obama ran a Brilliant Campaign in 2008. Unprecedented. Reporter and even with that unprecedented campaign, though, obama just barely edged out hillary clinton. This time, sanders says he is going to win several super tuesday states and keep pace with clinton in the delegate count. Thank you, nancy. See you on tuesday. President obama may reach across the aisle to get the senate to vote on his next Supreme Court nominee. Reports say the white house is considering nevadas republican governor to replace justice Antonin Scalia. Jan crawford is on capitol hill and watching the Supreme Court debate. Reporter good morning. Senator republicans say they will block anyone the president nominates even if its someone from their own party. Yesterday, the president predicted they will cave. I recognize the politics are hard for them. Reporter from the oval office, president obama suggested that eventually republicans will back down and give his Supreme Court nominee a shot. There is not a lot of vigor when they defend the position that they are taking that they wouldnt even meet, for example, with a Supreme Court nominee. They are pretty sheepish about it when they make those comments. Reporter across town, the senates top democrat, harry reid, offered a surprise pick, a rpublican. Nevada governor brian sandoval. If he were picked, i would support the man. Hes a good person. He has a great record. And he has been a tremendously good governor. Reporter sandoval may be seen as a moderate conservative but he is no fan of the president s signature achievement the Affordable Care act. He has called many aspects of the law unconstitutional and threatened to fight to have them overturned. In a statement, sandovals office said neither the governor nor his staff has been contacted by or talked to the Obama Administration regarding any potential vetting and that did not surprise utah senator mike lee. I dont think that is a legitimate rumor. I dont think it reflects any truth. I dont think that is who president obama is going to nominate. But even if it is, our position remains unchanged. Reporter lee says regardless of the nominee, most Senate Republicans are holding firm until the country elects a new president. Its not up to the president. We are a coordinate branch. Government. This is our discussion, not his. Reporter the president says the sandoval buzz is read and they are playing games. A republican to the Supreme Court would make a conservative majority on that court for a generation. Charlie . Thanks, jan. Apple ceo tim cook defended the company in his first interview about the standoff over the San Bernardino gunmans iphone. He calls the governments request to unlock it bad for america. Jeff pegues is in washington to show us apples case. Good morning. Reporter good morning. Apple executives and the tech giants attorneys say this is a slippery slope. Tomorrow the company will put its arguments in writing when its expected to file its legal challenge to the government. Some things are hard and some things are right. And some things are both. This is one of those things. Reporter speaking publicly about the controversy, apples ceo tim cook laid out his reasons for refusing a court order to unlock the iphone of syed farook, one of the terrorists behind the deadly attack in San Bernardino, three months ago. To oppose your government on something doesnt feel good. And to oppose it on something where we are advocating for civil liberties, which they are supposed to protect, it is incredibly ironic. Reporter cook says the decision would compel the company to write new software and create ago key that he says, in the wrong hands, could make all iphones vulnerable to hackers. Our smartphones are loaded with our intimate conversations, our financial data, our health records. They are also loaded with the location of our kids in many cases. Reporter cook says apple has cooperated with Law Enforcement, but contends investigators made a crucial error by telling farooks employer, San Bernardino county, to reset his icloud password. Apple says that limited the information that could be retrieved but even with the password change, the fbi says there may still be information on the phone that would not be accessible without apples assistance. If a court can ask us to write this piece of software think of what else they ask us to write. Maybe an operating system for surveillance, maybe its the ability for the Law Enforcement to turn on the camera. This is not what should be happening in america. I think this is going to be a question for the American People and their congress to decide if we want to make these Communications Devices immune to warrants when we know that they are used in crimes all the time. Reporter cook and bill gates agree that this issue will ultimately have to be decided by congress. Eventually, as it has been with the patriotic act, this will all be subject to democratic discussion. Reporter today, fbi director james comey will be on capitol hill where he is expected to discuss the governments case against apple. Norah . Jeff, thank you. The debate continues.

Reporter how confident is the syrian army right now . Well, enough to have a group of local journalists tour their latest victory. A half of a square mile of total destruction and five miles from the center of dah mass mumascud. This general leads the way through what used to be family homes that is a wreck now. A sniper was right here only yesterday, he says. We are in the suburb of daria. The army says 24 hours ago, it pushed the opposition fighters half a mile back to the next cluster of buildings. Now they are pounding them with machine guns and from the air. Overhead, the sound of the helicopters scouting its target. Then a strike. They are using barrel bombs, cheap and deadly. Are there any civilians left over there . No, he says. There arent. In fact, by now, almost everyone has fled. Bombs smashed this area to bits. The opposition fighters only survived by going underground into a network of tunnels. This is the road. The soldiers showing us around, this one explains this tunnel was under the main road.
