President Donald Trump is set to meet with Ukrainian President Volodymyr Zelensky on Tuesday and tell him it’s “time to end the war,” a White House official told the Washington Examiner.

Zelensky, who stopped in the United Kingdom on Monday on his way to Washington, D.C., is expected to attend the memorial for the late South Carolina Republican Sen. Lindsey Graham, who unexpectedly died earlier this month. Graham was a staunch Ukraine supporter who died shortly after returning from the war-torn country, and frequently called for both the Biden and Trump administrations to do more to help it.
