Trump sounded positive on Monday as he met with Ukrainian President Volodymyr Zelenskyy and European leaders at the White House, just two days after his summit with Russia's Vladimir Putin in Alaska. "I think President Putin will make peace. I think President Zelensky will make peace. We'll see if they can get along," Trump said.

The second Oval Office meeting in six months between U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy went off smoothly, in sharp contrast to their disastrous encounter in February.
