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.

The Ukrainian president says Monday's talks have been "constructive" as European leaders repeat calls for a ceasefire.

The president says he wants Zelensky and Russian President Vladimir Putin to meet alone before he joins them in a potential trilateral discussion.
