European leaders are to join the Ukrainian president during a visit that seeks a path to ending the war between Ukraine and Russia.

As Trump hosted Zelensky and European leaders to energize months of stalled efforts to halt the Russia-Ukraine war, the tone was far different than when Ukraine’s president was hounded out of the White House in February.

On Sunday, Secretary of State Marco Rubio, who sat in on the meetings with Mr. Putin at the American air base outside of Anchorage, disputed the idea that the Europeans were coming as a posse to protect Mr. Zelensky from a repeat of the February shouting match.
