poroshenko said now is the time for unity, and they would like to see a president-elected on may 25th. rather than split the vote, vitali klitschko said that he will run for kiev mayor, and he dropped out of the race. he was a favorite there. and he put his support behind petro poroshenko, and hopefully by not dividing the vote, poroshenkporoshenko will win tht round. yulia tymoshenko is seen as the old problem of politics and they may want someone new. the ex-boxer you vitali klitschko throwing his weight behind poroshenko. >> thank you. >>> in kabul the second attack in the capitol in the past 24 hours, and it comes a week before presidential elections. >> reporter: under a week until presidential elections when the taliban attacks again, the target this time the headquarters of the independent election commission in kabul. at least four fighters were disguised as women when they entered the house close to the commission building. afghan special forces and police reinforcements took their positions. >> forces in my house. i had three guards, two outside and one inside, but i don't k

you have petro poroshenko, who is a billionaire who made his fortune in chocolate. he's a likely candidate for prime minister. and then you have vitali klitschko, one of the frontrunners to be the next president. he's a retired heavyweight boxing champion. you said before no fight, no win. >> no fight, no win. >> reporter: so are you ready to fight? >> yeah, i fight for my country. i fight for the future. i fight for democracy, and i fight for the justice. and i'm not alone. >> reporter: when the billionaire petro poroshenko flew down to crimea on his private jet to negotiate, he was chased away by an angry pro- russian mob. this may be the revolution's biggest challenge yet-- a showdown with a much more powerful neighbor. do you want to see america take stronger action against russia? >> uh, my answer would be america should use all its instruments which they have at their disposal. >> reporter: including force? >> to stop the war. >> reporter: including force? >> all instruments. >> pelley: sounds like, clarissa he's asking the u.s. to intervene militarily? >> rep

klitschko forfeited the presidential match to his political partner petro poroshenko, one of the most respected figures in ukrainian politics. the may 25th vote takes place in a country both men describe as under russian occupation. >> people in the east south of ukraine who may be fearful of this election because of moscow, what message to you address to them? >> if you read our program, the special message to the east and south ukraine. the first message is security. the second message is the defending of all their rights including language rights, minority rights, everything. >> the deal prevented a division of forces among politician who is wanted closer ties with europe, an end of corruption and furious with the annexation of crimea. however, there will be another prime minister, yulia tymoshenko. >> she was officially nominated on assault and she, too, is promising a cleaner more responsive politics, but also to stand up to russia. >> if the people will trust me with the presidency i will never let any aggressor take our land without a fight. my aim is to demand cessation of the

>> both these candidates have been on several sides of major issue, but poroshenko was pro-nato membership, pro-european union membership, so my guess is he is the most likely of the two prominent candidates to move ukraine in the right direction, but nobody should underestimate yulia, and there are other candidates in this race as well, one of which is more pro-russian. so iy polls here can be discounted. i think this thing is up in the air. it may be that putin thinks he can do enough ballot box stuffing to get an outcome he wants, and that's why he's holding off on fourth military force. >> voter fraud? ukraine? we'll have to watch for that, too. john bolton, thank you for your assist as always. >> thank you, eric. >>> back here at home, march madness, pretty exciting stuff. then it turned out one school's diehard fans didn't taste last night's loss very well. we'll show you about the chaos that followed straight ahead. >>> plus obamacare sign-up deadline is just hours away. critics day the figures aren't all they're cracked up to be. >>> let's not be fooled here. it is broken, and peop

poroshenko told me about them trying with all their might to get negotiation or understanding with theussians, the ukrainian foreign minister is on his way to paris with secretary state kerry to try to talk to the russian foreign minister in paris who will meet with secretary kerry tomorrow. >> gloria, the political fallout in washington is intense. lipd s lindsey graham tweeted a while ago, it started with benghazi when you kill americans and nobody pays a price, you invite this type of aggression #ukraine. listen to tim murphy of connecticut. he's responding to all of these sharp allegations from republicans criticizing the president. >> what makes me even more suspect of the criticism of president obama is there doesn't seem to be any real difference here between what republicans want the president to do and what he is actually doing. it's easy to just say it's obama's fault but history tells us otherwise and these political attacks mask the fortunate fact that today there is pretty solid bipartisan agreement on what to do next. >> you know, i think senator murphy is right here. you
