US President Donald Trump holds a bilateral meeting with British Prime Minister Keir Starmer in the Oval Office of the White House in Washington, DC, on February 27, 2025. Starmer is meeting Trump to plead for a US backstop to any Ukraine ceasefire, insisting it would be the only way to stop Russia's Vladimir Putin from invading again. Starmer arrived in Washington late Wednesday to build on a visit by French President Emmanuel Macron, amid growing concerns in Europe that the US leader is about to sell Kyiv short in negotiations with Putin.
