WASHINGTON (AP) President Donald Trump said he would speak to Russian President Vladimir Putin on Tuesday as he pushes to end the war in Ukraine.

The U.S. leader disclosed the upcoming conversation to reporters while flying from Florida to Washington on Air Force One on Sunday evening.

“We will see if we have something to announce maybe by Tuesday. I will be speaking to President Putin on Tuesday,” Trump said. “A lot of work’s been done over the weekend. We want to see if we can bring that war to an end.”

Any such conversation could be a pivot point in the conflict and an opportunity for Trump to continue reorienting American foreign policy. European allies are wary of Trump’s affinity for Putin and his hardline stance toward Ukrainian President Volodymyr Zelenskyy, who faced sharp criticism when he visited the Oval Office a little more than two weeks ago.

Although Russia failed in its initial goal to topple Ukraine with its invasion three years ago, it still controls large swaths of the country.

Trump said land and power plants are part of the conversation around bringing the war to a close.

“We will be talking about land. We will be talking about power plants,” he said.

Trump described it as “dividing up certain assets.”

Trump special envoy Steve Witkoff recently visited Moscow to advance negotiations, and he said earlier Sunday that a call between Trump and Putin could come soon.

During his conversation with reporters on Air Force One, Trump said he was pushing forward with his plans for tariffs on April 2 despite recent disruption in the stock market and nervousness about the economic impact.

“April 2 is a liberating day for our country,” he said. “We’re getting back some of the wealth that very, very foolish presidents gave away because they had no clue what they were doing.”

Trump has occasionally changed course on some tariff plans, such as with Mexico, but he said he had no intention to do so when it comes to reciprocal tariffs.

“They charge us and we charge them,” he said. “Then in addition to that, on autos, on steel, on aluminum, we’re going to have some additional tariffs.”
