The United States is absolutely prepared to do what we can in what we must.

Vice President Harris today pledged support for Ukrainian refugees during her trip to Warsaw, Poland.

I frankly think that this exercise is not helpful... it's not in the United States interest to get into a conflict with another nuclear superpower.

There's no such thing as a no-fly zone over Ukraine, just as if we declared a no-invasion zone on the ground in Ukraine, the only way we could make that a reality is to put hundreds of thousands of US forces.

They constitute war crimes. They are attacks on civilians that cannot be justified by any -- in any way whatsoever.

Jen Psaki told me today that right now, his intention is still that U.S. forces are not going to go into Ukraine to fight Russian forces that maintains it.

the President's intention of sending U.S. military to fight in Ukraine against Russia has not changed.

We should continue to flow support and weapons and arms to Ukraine, but we should make sure that the weapons we're transferring are ones they can actually use, and are going to be the most effective and helping to defend our country.
