the fox moderators, he was asked about mitt romney's scathing attack this afternoon. regarding some of the things that he said in the past, and trump said that romney was a failed candidate. then he was asked about support that he had gotten from the ku klux klan. and then the attack over the fail failed. >> he's trying to go to the american voter what he did to the people on the course. it's our country is the stake. >> let me tell you who the real

conartist - excuse me. it's senator marco rubio. he was elected in florida. and who has the worst voting record in the united states senate. he doesn't go to vote. he's absent. now, the people of florida can't stand him. he couldn't get elected dog catcher. >> and he was also taken to task tonight on switching gears from everything from immigration to his support of anthony ray hinton. >> and tonight the moderators held donald trump's feet to the fire over numbers his campaign has put out. yes, they held his feet to the fire over numbers he spouted about cuts to the e.p.a. and came under assault from marco rubio, over his clothing

line and why it's manufactured in china not the u.s. >> he spent his time trying to convince america that he is something he is not. he inherited $100 million, and lost are more. he can start by announcing all the donald trump clothing will no longer be made in china and mexico, but will be made in the united states. crusaders got jabs in. >> marco rubio came on strong. we'll see what it does. as you heard, the donald trump, mitt romney feud was a topic of conversation at the debate. david shuster reports on that

war words. donald trump is a phoney, a fraud. >> in utah on thursday, mitt romney was unrelenting, the 2012 g.o.p. presidential nominee attacked trump as immoral and cool. you have his domestic policies lead to - his personal qualities means america would cease to be a shining city on the hill. >> romney listed the qualities. >> bullying, agreed, showing off. misonliany. the ab shirt third-grey theatrics. >> he failed horribly.

trump noted that it was loss that gave. >> mitt romney, go out and get him. you can do it. including his endorsement. >> i backed mitt romney. i backed him. you can see how loyal he is, he was begging for my endorsement. i could have said mitt drop to your knees, he would have dropped to his knees, he was begging. after that imagery, trump delivered this. >> mitt is, indeed, a choke artist. he choked like i never have seen any one. donald trump's momentum sparked panic among world and feel no cannes donald trump's rivals

agree. trump would have carried out the most elaborate conjob. do block trump. g.o.p. voter were urged. denying trump. i believe we can find a person who can win the election and representatives the values and policies of conservatism. mitt romney relates the very establishment that trump built his campaign against. and some strategists say it's likely that the attack may help

trump. when you watch a guys. >> chris christie that endorsed trump. the bigger picture. >> join us from markus phillips, is a former white house aid to president h w bush. the senior vice president. despite john's valiant attempts, it fell into the gutter and stayed there. thing of to this way, the only

chance to dislodge him is to take him down, they ganged un on him to do that. mitt romney made an effort. i think that he was making an effort to cast himself as the anti-trump. in the event of a brokered convention. he would be there and lay claim to the nomination bringing the party to victory. mitt romney spoke, chaos, melt down. some of the words in light of trump's success and mitt romney attacking them. is that fair. >> there's a lot of anxious.

some came to terms with the fact that donald trump could be the nominee, and main industry republicans did that already. there's more that have angst. and others that wonder what it means for them. you have to see what it means for them. in your district. if you are running for u.s. senator. you have to see what it means for you. for many republicans, it's not knowing. there's a lot to learn if donald trump is the nominee. he doesn't have a track record. at the same time. the unknown is a big fear. and they i can't not support trump.

at the end of the debate. the three candidates said they would support donald trump, and she said he would support the other three. that would be good news if what romney talked about, trump goes into the convention without a majority, and somehow someone else ends up getting nominated. >> that's yet to be seen. it will be a slug fest. march 15th, before march 15th they had perfect primaries and states. donald trump leads in the deep south, louisiana, mississippi, you have a bunch of primaries coming up before that march 15th date. where out of two of the primaries, ohio and florida are winner take all. they are the home states for john kasich, and marco rubio. they are must wins for both of them. they are big, big days and lots

are at stake on the days. it will be hard to dislodge donald trump, and we'll see if the impact had any impact on the polling numbers, and whether the speech has income. >> it may feed fuel to the fire of supporters, and the rejection of traditional world, as we go into the upcoming states, trump is ahead n every poll. in most by double digits. unless there's a shift and as you said rubio and john kasich win interstate. it's likely he'll have the most dell dates. >> that's right. the most by the convention. mitt romney, of course is positions himself to take up the

>> porter is the first of six officers. he was not involved in gray's arrest and not driving the van where gray suffered injuries. in disease, the trial ended. his retrial was set in june. prosecutors want to call him as a witness. second degree murder. the federal court has had cases. because border has been granted immunity in exchange for his testimony, he should testify, what he says in other trials

can't be used against him. porter's defense team was not buying it. forcing him to testify against the other officers puts him at risk of being called a liar. and community would not work. sergeant's centers are adverse they'll have to cull him a liar. the testimony could turn jurors against him. he is a defendant. see if you can prove it beyond a reasonable doubt.
