President Trump spoke with French President Emmanuel Macron ahead of a European leaders’ meeting about the war in Ukraine, as the Trump administration is pressing forward with plans to negotiate an end to the war.

A White House official said the call Monday was “friendly” and lasted about 30 minutes.

The two presidents talked about the Ukraine war, meetings among European leaders and the talks in Saudi Arabia between U.S. and Russian officials, according to the official.

Macron pulled together the Monday summit, which comes after Trump said he expects to meet face-to-face with Russian President Vladimir Putin, implying that they are probably going to meet first in Saudi Arabia.
