President Donald Trump said in a rare admission of error that he had thought his recent sit-down with Russian President Vladimir Putin would lead to the end of the war on Ukraine.

“I thought I had it done,” Trump revealed in an interview with The Daily Caller published Saturday.

The president met with Putin in Alaska earlier this month for negotiations to put hostilities in Ukraine to an end. Trump came away empty-handed, but claimed the next day that they had discussed a “Peace Agreement” together, which has yet to publicly materialize.

Trump sat down for an hour-long conversation Friday in the Oval Office with Reagan Reese, the conservative outlet’s White House correspondent. He said Putin is unlikely to meet with Ukrainian leader Volodymyr Zelenskyy anytime soon.

“We’re not talking about something that I started. I inherited this war. And all I’m trying to do is put out the flame, you know. And I thought I had it done,” Trump told Reese, adding that he has previously “done it with wars that were tougher than this.”
