US President Donald Trump and Ukraine's Volodymyr Zelensky held a highly publicized meeting in the Oval Office on Monday as European leaders arrived in Washington for high-stakes talks on ending the war in Ukraine.

It was a striking contrast to the meeting six months ago, when Trump, red-faced and angry, accused an agitated Zelensky of failing to show enough gratitude to the United States. The blowup was so heated that the Ukrainian delegation was sent from the White House without being allowed to eat their waiting lunch.
