President Donald Trump has left Vietnam, after a second summit with North Korean leader Kim Jong Un ended with no agreement.
The first signs things weren't going to plan came when the two leaders were late for a scheduled working lunch.
Reporters who had been called to cover the event, one of several brief opportunities to ask questions of the two leaders, were told instead Trump and Kim would be heading back to their respective hotels.
Trump's press conference was brought forward by two hours, replacing what should have been a signing ceremony attended by both leaders.
Shortly beforehand, the White House released a statement saying the talks had ended with no agreement reached.
At the presser, Trump said this was because of a disagreement over sanctions relief. He remained optimistic for further progress in the future, but said "sometimes you have to walk away."
That's what he's now done, heading back to Washington, where the drama from his former lawyer Michael Cohen's testimony before Congress awaits him.
Meanwhile, Kim remains in Vietnam, where he is due to begin an official state visit Friday.
Trump has promised to phone South Korean President Moon Jae-in on his way back to the US, and also to brief Japanese Prime Minister Shinzo Abe on the failed talks.
