President Donald Trump welcomed Ukrainian President Volodymyr Zelenskyy to the White House for a high-stakes meeting as the U.S. president pushed for a deal to end Moscow's war on its neighbor. A host of European leaders joined the pair.

Trump didn't rule out the possibility of American troops' helping to guarantee peace between Ukraine and Russia should the leaders reach an agreement.

Zelenskyy and Trump expressed hopes that talks with Ukrainian and European leaders at the White House could lead to trilateral talks with Putin to bring an end to his war on Ukraine.
