Trump-Putin summit: Zelenskyy to travel to DC on Monday to meet with President Trump

Kremlin spokesman Dmitry Peskov, in a Russian state media readout, previewed a potentially long meeting between the U.S. and Russian delegations.

"We are proceeding on the assumption that there will first be a one-on-one conversation. It turns out that this will be attended by aides. Then there will be negotiations between the delegations, possibly in the form of a working lunch. Then the leaders will leave for a while and then gather for a joint press conference," Peskov said.

"In general, we can imagine that it will take at least 6-7 hours," Peskov said.

President Donald Trump told reporters on his flight to Alaska that if progress is made in his meeting with Putin, he would consider talking about business deals with Russians. Trump said the Russian president is bringing a lot of business people from Russia to Alaska, but said that nothing will be done until the war is done.

"If we make progress, I would discuss it, because that's one of the things that they would like. They'd like to get a piece of what I built in terms of the economy," Trump said.

"And I noticed he's bringing a lot of businesspeople from Russia, and that's good. I like that, because they want to do business, but they're not doing business until we get the war settled," Trump added.

Excluded from Friday's summit, Ukrainian President Volodymyr Zelenskyy said ahead of Trump and Putin's meeting that he is counting on the United States.

"Today, I also expect a report from our intelligence on the current intentions of the Russian side and its preparations for the meeting in Alaska. Indeed, high stakes," Zelenskyy said. "The key thing is that this meeting should open up a real path toward a just peace and a substantive discussion between leaders in a trilateral format -- Ukraine, the United States, and the Russian side. It is time to end the war, and the necessary steps must be taken by Russia. We are counting on America. We are ready, as always, to work as productively as possible."

President Donald Trump told ABC News Senior Political Correspondent Rachel Scott he's going to talk with Vladimir Putin about Russia's overnight strikes during Friday's meeting. Trump said he believed the strikes hurt the Russian leader ahead of their talks.

"I think they're trying to negotiate. He's trying to set a stage. I mean, in his mind, that helps him make a better deal. It actually hurts him. But in his mind, that helps him make a better deal, if they could continue the killing. Maybe it's a part of the world, Maybe it's just his fabric, his genes, his genetics, but he thinks that makes him, gives him strength in negotiating. I think it hurts him, but I'll be talking to him about it later," Trump said aboard Air Force One.

Russia attacked Ukraine with two ballistic missiles and 97 drones, the Ukrainian Air Force said on Friday morning.
