What controversial claim did Donald Trump make about the war in Ukraine?

Donald Trump falsely claimed that Ukraine and Ukrainians started the war, echoing Russian talking points. This controversial statement came shortly after a US delegation met with Russian negotiators in Saudi Arabia to discuss plans to end the conflict, notably without any Ukrainian representatives present. Trump's repetition of Russian narratives about Ukraine has raised serious concerns as it contradicts the established fact that Russia invaded Ukraine. His comments are particularly significant given the ongoing diplomatic efforts regarding the war, where Ukraine—the country that was invaded—was excluded from crucial negotiations about its own future.
