President Trump expressed skepticism on social media, stating, "Is it really possible that big progress is being made in Peace Talks between Russia and Ukraine??? Don't believe it until you see it, but something good just may be happening.

Secretary of State Marco Rubio expressed optimism after meeting with Ukrainian leaders to discuss the Trump administration's peace plan, despite concerns over the proposal's concessions to Russia.

Russian President Vladimir Putin on Monday said the current US peace proposal that heavily favors Moscow could “form the basis for a final peace settlement” in Ukraine.
