GOP Rep. Mike Turner of Ohio expressed concern Sunday that the White House-backed proposed plan to end the war in Ukraine is too pro-Russia, while urging that any peace arrangement must look at Russia as a “skeptical adversary.”

Turner said on “Face the Nation with Margaret Brennan” that the president’s “goal of peace is incredibly important,” while acknowledging comments made by Secretary of State Marco Rubio’s supporting a sovereign Ukraine as negotiators gathered in Miami on Sunday morning.
