Russia has threatened to change its stance in peace talks, which could jeopardize U.S. hopes for a deal in the near future.

President Donald Trump appeared to signal his displeasure with Russian President Vladimir Putin by sharing a New York Post editorial that sharply criticizes the Kremlin and argues Trump should "turn up the heat" on Russia.

Trump and Zelenskyy held talks at Trump’s Mar-a-Lago residence Sunday and Trump spoke with Putin by phone after the meetings. Trump said a peace deal was “getting a lot closer, maybe very close” following the negotiations, though Russia and Ukraine have accused each other of continuing to exchange fire.

Trump and Russian President Vladimir Putin spoke by phone shortly before the meeting. Trump described it as a “good and very productive telephone call.”

Advisers to Zelenskyy recalled the last in-person meeting with Trump, in October, which was preceded a day earlier by a call between the US and Russian presidents. In the White House the next day, Trump grew frustrated with Zelenskyy and his team, and tossed aside maps of the front line in Ukraine.

As peace talks between Russia and Ukraine are underway, North Carolina’s Thom Tillis joined other senators sending the warning to President Donald Trump after a Christmas attack.

Donald Trump and Volodymyr Zelensky hailed progress on ending Russia's war in Ukraine at their Florida meeting in Mar-a-Lago.

Ukrainian President Volodymyr Zelensky said the attack, which comes ahead of his latest talks with US leader Donald Trump, shows that Russia has no intention of ending the war.
