President Donald Trump is scheduled on Monday to welcome Ukrainian President Volodymyr Zelenskyy to the White House for a high-stakes meeting as the U.S. president pushes for a deal to end Moscow's war on its neighbor. A host of European leaders will join the pair.

The day of meetings follows Trump's Friday summit with Russian President Vladimir Putin in Alaska -- and it comes about six months after an explosive Oval Office meeting between Zelenskyy, Trump and Vice President JD Vance.
