Marie Yovanovitch: “Putin has had an obsession about Ukraine, an obsession to get Ukraine back into the Empire.”

I think they underestimated the international wealth and resolve of the United States and the allies and partners that I think President Biden has done a great job of bringing together.

Well, I think it's hugely important for two reasons. One is to focus on what is happening in Ukraine, to call out Russian actions for what they are, war crimes, as we just heard the president declare, demand a cease-fire and warn Putin not…

Well, I think it just shows that President Trump was using Ukraine as a pawn for his own personal reasons.

It is really horrifying. And I think that it's important that we not allow Putin to set the conditions for this war.
