It comes as the White House says Friday's meeting with the Russian president in Alaska will be a "listening exercise" for Trump.

Volodymyr Zelensky said in a new interview that he believes Vladimir Putin will significantly "benefit" from his meeting with Trump.

President Donald Trump said he will meet with Russian President Vladimir Putin next Friday in Alaska to discuss ending the war in Ukraine, a potential breakthrough after weeks of expressing frustration that more was not being done to quell the fighting.
