Rep. Seth Moulton (D-Mass.) on Monday said whether President Trump wants Ukraine to win the war against Russia is an “open-ended question.”

“I think it’s still an open-ended question, because — just because Donald Trump is saying the right thing in the last 24 hours, it doesn’t make the last six months go away,” Moulton told NewsNation’s Blake Burman on “The Hill.”

“But listen, I’m happy with where Trump is today. He seems to make decisions based on politics, not on principle, even when you just heard him talking about this, he wasn’t talking about the principles of democracies overcoming murderous dictators. He was just talking about who pays the bill,” he added.

Trump recently said the United States will impose “severe” tariffs against Russia if the country does not go along with a ceasefire in Ukraine within the next 50 days.

“We’re very, very unhappy with [Russia], and we’re going to be doing very severe tariffs if we don’t have a deal in about 50 days,” Trump said amid an Oval Office meeting with NATO Secretary General Mark Rutte.

The president signaled he would impose a 100 percent “secondary” tariff targeting other nations that do business with Russia.

Since the start of his second term, Trump and his administration have pushed for an end to the war in Ukraine but have not experienced much success.

Russia invaded Ukraine over three years ago after Moscow built up troops at the border. Trump campaigned on a vow to end the war in 24 hours, a timeframe he later stated was “sarcastic.”

“Trump’s newfound support for Ukraine is a sharp reversal from when he was parroting Putin’s propaganda—and it’s long overdue,” Moulton said in a post on the social platform X Monday.

The Hill has reached out to the White House for comment.
