that where he went today and was greeted by a crowd of 10,000. >> i believe that donald trump's idea of dividing us up is a horrific, un-american idea. >> reporter: he wasn't the only one talking about the latest twists in the g.o.p. race. >> you wouldn't know anything about it because you're a lousy businessman. >> i don't know anything about bankrupting four companies. you bankrupted four companies. >> reporter: the voters we met were transfixed, too. >> i don't want my son to look at those debates and think that's the way he should behave in society. >> reporter: malcolm harris is a veteran and former republicanan >> it doesn't look likeke a party. it looks like a w.w.f. fight going on, on stage, and no policies. none. >> reporter: there is a sign that sanders does not expect to close the gap is right behind me

proposed in this memo that was circulated last fall to top donors, including billionaire sheldon adelson. "if trump wins," it says, "everyone loses." trump's opponents do seem to have unified around calling on him to release his tax returns to up the pressure. rubio o day p pvided forms showowg he and his wife made $2.3 million from 2010-2014 and paid about $526,000 in taxes, but, jim, these are just summaries of those filings. they're not the complete returns, like hillary clinton has provided and like mitt romney provided in 2012. >> axelrod: julianna goldman with the latest on the republican side of the race. thank you. senator ted cruz has promisedded to release his tax returns soon, and he's pressing donald trump to do the same. in an interview with john dickerson for "face the nation," cruz suggested trump's refusal to show his returns raises ethical questions. >> why is it a problem if he doesn't release his taxes? >> well, he said in the debate, he said, "gosh, i'm being audited for two years," then he

maybe five years. lilien, if there's a proem in his taxes the voters have a right to know because ce september, october, the general election, folk in addition the media are going to make a heyday about any problems with his taxes and i think primary voters have a right to know. >> axelrod: you can see the rest of john's interview with ted cruz tomorrow morning on "face the nation." donald trump, marcoubio, and bernie sanders are also scheduled to appear. the town of hesston is still reeling two days after a gunman killed three people at a plant plante and wounded 14 of 14 others before police killed him. >> reporter: zach naylor returned to excel industries today for the first time since the shooting, a bullet pierced hihi foot. >> i'm upset that we lost some close people that we work with every day. it's hard to deal with. >> reporter: three of his coworkers were killed, including his friend joshua higbee, who was trying to save others.

a hero than anybody because he died trying to save someone else. >> reporter: loretta sadowsky's son, brian, was also kikied. >> when hehe didn't answer me,e usually does, and about 10 minutes, i sent him another text, and said, "please call me." and i never heard another word from him. >> reporter: police say cedric ford's rage was triggered by a protective order taken out by an ex-girlfriend. he carjacked and shot people as he made his way to the plala thursday and fired at random. d.j. britton is in intensive care after he was shot through the leg. the suspect was not only his coworker, his parents' dentist lived two doors down from ford. >> he heard a pop and went straight to the floor, and that's when he realized he'd been shot. >> reporter: ford was a convicted felon. investigators say the weapons he used in the attack, an assault rifle and piol, were given to him by a former girlfriend,

but overall, day one has gone better than anyone expected, although, of course, there is no official monitoring. we went down into the center of damascus to a park that's both a campsite and a hangout for some of the thousands of syrians who had to flee from other areas. and like everyone else whose lives have been shattered by the war, they hope today'y' lull might actually somehow lead to lasting peace. they are tired, and they just want to go home. throughout the day, there were several reports of violations, rebel groups accuse the army of breaking a truce, but there are no major incidents. russia actually grounded its bombers for the day. but president putin has only promised a 24-hour pause, so it is quite possible those russian planes will be in the air again tomorrow hitting the al qaeda-linked nusra front, and isis fighters. the two groups that were
