We will judge Russia and the separatists not by their words, but by their actions.

With U.S. help, newly vetted and trained police officers are now patrolling the street of Kiev, Odessa, Lviv, and Kharkiv.

I think our European allies, Germany and France, are working very hard, but I think that the United States should be engaged there as well.

If there are no consequences for Russia not to keep their commitments other than that which exists, there is not necessarily a reason for them to pursue their commitments.

Look, I want to focus on the reality. We had the IMF managing director here in a private session with the members of the committee...

The Budapest Agreement where we gave Ukraine security assurances if they gave up their nuclear weapons that we would protect their territorial integrity, that has not worked out too well for them.

We do have an obligation to fulfill it, and in that context, Ukrainians are saying, please help us, let us defend ourselves.

I personally have been an advocate, as I think the majority of this committee has, of providing lethal weapons to the Ukrainians--lethal defensive weapons to the Ukrainians.

Putin's vision and his long-term goals and intentions, I think, have been very clearly stated and had not changed.

I personally believed that lethal defensive weapons should be considered for Ukraine.

Ukraine needs serious military aid and assistance to be able to defend its territory and to push back against these Russia-backed separatists.

Minsk remains a goal worth fighting for because the alternatives for Ukraine are bleak.
