[ cheers ] >> mitt romney lays into republican front runner, donald trump. maryland's highest court hears arguments against the officers charged in the death of freddie gray. and reports of north korea firing short-range rockets just hours after new international sanctions are imposed.
♪ this is al jazeera america live from new york city. i'm richelle carey. former republican presidential nominee, mitt romney has jumped into the republican civil war, attacking g.o.p. front runner, donald trump's character, calling him a fraud and a phony. >> there's plenty of evidence that mr. trump is a conman, a fake. mr. trump has changed his positions not just over the years, but over the course of the campaign, and on the ku klux klan daily for three days in a row. we will only really know if he is a real deal or a phony if he releases his tax returns. >> donald trump tweeted, of course, that he would be in the air the next two hours, flying to a campaign event in maine. however, earlier he tweeted
this: and then speaking on msnbc this morning, trump said that romney, that's a quote, for his endorsement in 2012. >> he failed at his campaign. it was a horribly-run campaign. he was a disaster the last month, month and a half. he wasn't on television. it was almost like he was lost, and he ran one of the worst campaigns as you know in presidential history. in that was an election that should have been won by the republicans. he was a catastrophe. >> joining me now is david shuster. >> remarkable, right? >> shocking that donald trump would speak of mitt romney that way. but obviously no one knows whether or not he begged for his endorsement. but four years ago, mitt romney put out there that donald trump was endorsing him, and now he makes -- just ethered him today.
>> mitt romney in 2012 called donald trump a great job creator. and now he is saying he inherited everything. mitt romney didn't even address his previous remarks. but there's a deep divide in the republican party not over whether donald trump is acceptable. a lot of the establishment think he is simply unacceptable. the question is how do you contain him? do you contain him by beating him? or do you contain him by working with him, by working with him. a lot of republicans think it's too late. you can't beat him. the best thing we can do is try to work with him. some members of congress saying i can work with donald trump, and then there are those, like mitt romney and a lot of people who are throwing up a lot of money saying no, we still have a chance to beat him. we are going to throw everything we have, and that's what mitt romney was doing today. >> so he is saying let's throw our support behind one of the
other candidates, but does the republican party if they want to stop donald trump need to pick one candidate? >> and that's exactly the rub. perhaps in a head-to-head matchup there's a chance that that other candidate could win the majority of the rest of the states, and it's winner take all. but that's the problem, as long as we have marco rubio maybe winning florida, john kasich maybe winning ohio with a very big maybe on it, because they haven't won so far except for the caucuses that went to rubio, donald trump as long as he has other candidates in the race, he can still get a majority of the delegates, and win most of the delegates with a simple plurality victory, and until they get back to head-to-head, it's hard to see how the math would work in anybody's favor but donald trump. >> so why the hesitancy to unite
behind one candidate? >> great question again, because marco rubio believes that he is the one who deserves to go to florida in two weeks and win florida. john kasich says i'm the guy that can win ohio, and ted cruz says i'm the guy that has beaten donald trump in primaries. the republican party cannot decide which of the three it should be. their egos are huge. they think they are the anti-trump and there's no way of convincing them to get out. >> is it an overstatement to say this is an existential fight. >> i think that's true. if he wins the white house, donald trump is pledging to change republican policies on foreign policy, the economy, on entitlement programs -- >> and that's if he means those things because he flip flops so
much. >> he may put in place policies that republican old guard has to spending the next 30 years trying to unwind. they hate him for a lot of reasons, but they also hate the idea of hillary clinton in the kwhooits, and if donald trump can convince them that he has a chance of beating hillary clinton if he has got the nomination, it's hard to see how you deny him of that. because then you can cause the republican party to implode and have no chance in the fall, because all of the donald trump supporters will say, to hell with it, we're going with somebody else or stay home. >> so 1:30 is when we will hear donald trump's response. >> it will be colorful. >> yeah, it will. >> david thank you so much. >> meanwhile the republican presidential candidates will face off again tonight in detroit. ben carson says he will not
attend the debate after landing another the bottom in super-tuesday votes. six states are holding primaries or caucuses this weekend. michigan is the biggest prize because it has 59 g.o.p. delegates up for grabs. john kasich's flailing campaign is hoping for a strong showing in michigan. he is already there holding events, and this morning he got a boost. the detroit news endorsed him. but he is far behind in delegates and so is marco rubio. diane eastabrook reports. >> reporter: marco rubio got a super star welcome in michigan one day after a bruising super-tuesday, less than a week before the michigan primary, the florida senator appealed to a crowd of nearly a thousand near detroit to block donald trump's path to the republican presidential nomination. >> what people are saying is please, everyone get together so we can keep this front runner
from winning and destroying the republican party. [ cheers and applause ] >> believe me i am a unifier. >> reporter: trump is on a roll. he also has a commanding lead going into michigan's primary next week. stopping occasionally while supporters chanted his name, rubio blasted trump for praying on voter's fears. michigan has shed more than 200,000 manufacturing jobs in the past decade. >> these jobs are being sent to other countries, or they just don't pay enough anymore. times are difficult. we have to acknowledge that reality, but we should not take advantage of that reality. >> michigan defies easy labels, it is a traditional blue collar
state, but it also is a state with a lot of independent voters. >> he is probably the most christian of the bunch. >> i have been listening to his debates and what he wants to do for this country, i think it is going to make this country the great estrogen. >> i think he'll win michigan. i do. >> reporter: but some admitted they could still be swayed by trump. >> we were kind of just wetting our feet into this whole arena, so time will tell. >> reporter: michigan voters will get one more chance to see rubio, trump, ted cruz, and john kasich debate before heading to the polls. it could be rubio's best shot at getting them into his corner. >> thank you, and god bless all of you. thank you. [ cheers and applause ]
>> diane eastabrook, al jazeera, michigan. as for the democrats they are looking ahead to contests this weekend. hillary clinton widened her lead on super-tuesday, bernie sanders did win four contests and is trying to mount a comeback. he was in michigan this morning and spoke about the current unemployment crisis. >> corporate america made the decision that they didn't want to pay workers in this country a living wage, provide health benefits, protect environmental standards, negotiate with trade unions. they didn't want to do that. what they wanted to do was shut down plants in america, go to mexico, go to china, go to desperately poor countries, hire people for pennies an hour, and then bring their products back into america. you didn't need to have a phd in economics to figure that one out. >> 11 key states are up for
grabs for the next two weeks for clinton and sanders. hillary clinton has a big lead in the delegate count as you can see there, however, in what could be a blow to the clinton complain, the justice department has offered immunity to a former state department staffer who set up her private email server. in 2009 he set up the server in her home in new york. the fbi is investigating whether clinton mishandled classified information. a spokesman for the clinton campaign said they are pleased he is cooperating with the investigation. new tensions today along the korean peninsula. south korea says the north has fired six, short-range projectiles. they were launched on the east coast. it happens hours after the u.n. security council approved the toughest sanctions on pyongyang in more than two decades. those sanctions followed a
recent nuclear test by the north. as harry fawcett reports on what reporters were told. >> reporter: in that news conference, the ministry of defense simply saying a number of projectiles had been fired into the sea off of the sowern coast of the korean peninsula. the local media are reporting a little bit more fully. they sometimes get briefings from unnamed military officials. they are talking about a range of apparently 100, to 150 kilometers. various numbers have been mentioned, six or eight to nine, projectiles. unclear how they were launched. it's understood analysis is underway on that point. the ministry of defense is saying it military remains in a heightened state of readiness,
watching out for any further actions by its counterparts in north korea. we are coming into a period of annually height owned tensions between the north and south, because military exercises are expected to get underway on the korean peninsula. this year it is expected they are to be bigger than usual, and may influence rehearsals against a presumptive strike against north korea. and north korea says it reserves the right to attack south korean seats of government. we expect a round of heightened tensions. this is the first north korean reaction to this resolution passage. it may well be that there is more to follow in the days and weeks to come. the burden of enforcing the new sanctions will fall largely on china, north korea's largest trade partner. up next, the freddie gray
