U.S. President Donald Trump welcomed Russian President Vladimir Putin for groundbreaking talks that could decide whether a truce is possible in Europe’s deadliest conflict since World War II.

Earlier on Friday, Trump said that he would walk away from his summit with Putin if the talks went poorly.

Fox News previewed the comments on U.S. social media company X, citing an interview with anchor Bret Baier in which Trump said he "would walk" if the meeting did not go well.

"We’re going for a meeting with President Putin in Alaska. And I think it’s going to work out very well and if it doesn’t, I’m going to head back home real fast," Trump was quoted as saying by FOX News White House Correspondent Jacqui Heinrich on X.

Earlier in the day, Trump told reporters aboard Air Force One that any possible territorial swaps between Ukraine and Russia would be up to Kyiv to decide.
