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 did not rule out the possibility of American troops helping to guarantee peace between Ukraine and Russia should the leaders reach an agreement.

Zelenskyy at the start of the meeting presented a letter from his wife, Olena Zelenska, for Trump’s wife, Melania. The U.S. first lady over the weekend sent a letter to Putin urging him to consider the children impacted by the conflict and bring an end to the brutal 3 1/2 year war.
