President Donald Trump and Russian President Vladimir Putin spoke by phone Thursday, but neither side reported any breakthrough on efforts to end the war in Ukraine.

Trump, who promised on the campaign trail that he could end the war on his first day in office, has been repeatedly frustrated in his efforts to secure an agreement to end the fighting.

“It was a pretty long call. We talked about a lot of things, including Iran. We also talked about the war with Ukraine and I’m not happy about that,” the president said before boarding Air Force One for a trip to Iowa for an event celebrating the nation’s 250th anniversary.

“No, I didn’t make any progress,” he said in response to a follow-up question about discussions on a deal to end the war.

The White House did not provide a readout of the call. But Putin aide Yuri Ushakov said the two leaders did not discuss a recent pause in weapons shipments to Ukraine, which was first reported by POLITICO, in the nearly two-hour long conversation.

When asked about the pause, Trump delivered an ambiguous answer, saying: “We haven’t. We’re giving weapons. But we’ve given so many weapons. But we are giving weapons and we’re working with them and trying to help them. But we haven’t.”

He added that former President Joe Biden “emptied out our whole country giving them weapons,” and that the U.S has to “make sure we have enough for ourselves.”

Trump plans to speak with Ukrainian President Volodymyr Zelenskyy on Friday.
