U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy's meeting in the Oval Office was notably different from their last encounter in February.

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.
