Happening now, breaking news, crucial phone call at any moment. President Trump is set to speak

with Russian President Vladimir Putin on ending the war in Ukraine, but it comes just one day.

After Russia launched its largest drone attack on Ukraine since the war began more than three years

ago. Quote, cancer touches us all.

That's what former President Biden is saying after being diagnosed

with what's described as an aggressive form of prostate cancer.

Welcome to our viewers here in the United States and around the world.

I'm Wolf Blitzer with Pamela Brown and you're in the Situation Room. We begin this hour with breaking news.

At any moment, President Trump is set to speak by phone with Russian leader of Vladimir Putin to push for an end to Russia's

war in Ukraine. President Trump has said he believes peace isn't achievable without the two men

speaking directly. Yet over the weekend, Russia unleashed its largest drone attack on Ukraine

since its illegal invasion more than three years ago. After the Putin phone

call, President Trump is due to speak with the Ukrainian president, Volodymyr Zelensky, and then

some NATO leaders as well. Let's go live right now to CNN White House reporter Elena Treene.

Elena, realistically, what is President Trump hoping to accomplish in these phone calls?

Yeah, like, I mean, obviously the ultimate goal here, Wolf, would be to eventually get both sides to agree to a ceasefire.

But in the near term, the question really, and this is increasingly what I'm hearing from Trump administration officials, is to figure out whether or not something

like that is even possible, whether or not Vladimir Putin, Russia's president, is actually serious

about getting to a point where he is willing to try and begin the beginning of this process

to find peace. Now, that is essentially what is going to be the key question today at 10 a.m. when the president actually speaks with Putin by phone, according to Vice President J.D. Vance. Listen to how he put it, though, when asked this directly by reporters. The president's been very clear. This is not the United States is not going to spin its wheels here. We want to see outcomes. The talks have been proceeding for a little while. We realize there's a bit of an impasse here. And I think the president's going to say to President Putin, look, are you serious? Are you real about this? Because the proposal from the United States has always been, look, there are a lot of economic benefits to thawing relations between Russia and the rest of the world,

but you're not going to get those benefits.

You keep on killing a lot of innocent people.
