WASHINGTON (Reuters) -Friday's Alaska summit between U.S. President Donald Trump and Russian President Vladimir Putin "is a listening exercise for the president," the White House said on Tuesday, tempering expectations for a quick Russia-Ukraine ceasefire deal.

Trump has met in-person with Zelensky at least three times since returning to office, including a Feb. 28 meeting where he lashed out at the Ukrainian president and accused him of prolonging Russia’s invasion. The two leaders met again on April 26 on the sidelines of Pope Francis’ funeral and in The Hague on June 25.
