Biden-Putin summit highlights: 'I did what I came to do,' Biden said

The summit between the two presidents ended earlier than expected. Biden was the first to leave -- giving a thumbs-up to reporters as he walked out.

He departed Villa La Grange for his hotel in the "Beast," the armored presidential limousine that had been idling outside.

The two men spent two hours and 38 minutes meeting together, according to the White House -- shorter than up five hours White House officials said their encounter might last.

Next, Putin is expected to hold a news conference. Biden will wait to begin his own press conference until his counterpart's concludes.

A White House official said the expanded bilateral meeting broke at 5:05 p.m. local time (11:05 a.m. ET), after a little more than an hour.

The two men spent two hours and 38 minutes meeting together in total, according to the White House -- shorter than the four to five hours the Biden administration said it expected it to last.

Biden's ride, the Beast, is staged outside the Villa.

The second meeting was going to be broken into two parts -- with a break splitting up the two parts -- but the official said that it was all just one long part.

It appears the leaders are done meeting for the day.

White House officials have significantly downplayed the prospect of a prisoner swap for two U.S. Marine veterans, Trevor Reed and Paul Whelan, being held in Russia, ahead of the meetings.

"That's certainly something the Russians have been pushing for," said ABC News Chief White House Correspondent Cecilia Vega. "They have basically said this could encourage the Kremlin to target more Americans unfairly like they believe these two Americans there were targeted."

Russian officials have indicated they would like to trade Reed and Whelan for two Russians held in the U.S.: Viktor Bout -- one of the world's most notorious arms dealers and dubbed "the Merchant of Death" — and also Konstantin Yaroshenko, a pilot currently serving a lengthy jail sentence for a drug smuggling conviction.

Whelan's family overnight released an audio message from him recorded from the prison camp in central Russia where he is held. In it, he appealed to Biden to help free him.

A White House official confirmed the expanded bilateral meeting started about an hour ago, at 4 p.m. local time (10 a.m. ET).

ABC News Correspondent Karen Travers said the summit is about setting the U.S.-Russia relationship on a new path forward to a more stable, predictable relationship.

"In terms of the stakes, it's been striking to hear officials on both sides say over the last few days heading into this summit that there are very low expectations for some major breakthrough between President Biden and President Putin," Travers said. "This is all about starting a conversation."

She also noted how different this meeting looks from President Donald Trump's encounter Putin in Helsinki in 2018, and the two took questions standing side-by-side at a joint news conference.
