SULLIVAN: I can level with the American people in saying that war is unpredictable.
One year ago, we were all bracing for the fall of Kyiv in a matter - in a matter of days. One year later, Joe Biden was standing with President Zelenskyy in Kyiv declaring that Kyiv stands.
So, I cannot predict the future, and nor can anyone else. And anyone who is suggesting they can define for you how and when this war will end is not leveling with the American people or anyone else.
What I can say is that the United States is going to continue to marshal this wide international coalition of countries to provide Ukraine with the tools that it needs to defend itself and to take back territory that the Russians have occupied. And we are prepared to do that. We have the staying power for that. We have proven we can sustain unity.
We have proven that we can sustain this level of effort. And President Biden went to Kyiv to indicate that our support will be unwavering.
BASH: Before I let you go, I want to ask about a new "Wall Street Journal" report out this morning that a classified intelligence report from the Department of Energy concludes that the coronavirus pandemic most likely did not emerge naturally, but it did come from a laboratory leak.
Did the coronavirus pandemic start in a lab? Is that what you believe now?
SULLIVAN: Well, Dana, there is a variety of views in the intelligence community. Some elements of the intelligence community have reached conclusions on one side, some on the other. A number of them have said they just don't have enough information to be sure.
Here's what I can tell you. President Biden has directed repeatedly every element of our intelligence community to put effort and resources behind getting to the bottom of this question. And one of the things in that "Wall Street Journal" report which I can't confirm or deny, but I will say the reference to the Department of Energy, President Biden specifically requested that the National Labs, which are part of the Department of Energy, be brought into this assessment because he wants to put every tool at use to be able to figure out what happened here.
And if we gain any further insight or information, we will share it with Congress and we will share it with the American people. But, right now, there is not a definitive answer that has emerged from the intelligence community on this question.
BASH: Jake Sullivan, the president's national security adviser, thank you so much for joining me this morning.
SULLIVAN: Thanks for having me, Dana.
