Ukrainian President Volodymyr Zelensky said his bilateral meeting with US President Donald Trump in the Oval Office on Monday was "very good" and "constructive," as European leaders met with the US leader to discuss security guarantees for Kiev.

President Trump and Ukrainian President Volodymyr Zelensky held a much more cordial Oval Office meeting in front of TV cameras Monday than the fiery eruption that took place in front of the room’s fireplace 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.
