Ukraine needs to rein in criticism of the United States, which is trying to secure a peace deal acceptable to all sides, White House national security adviser Mike Waltz said Thursday in an interview.
"They need to tone it down and take a hard look and sign that deal," Waltz told Fox News, referring to a critical minerals deal with Washington.
At the same time, Waltz said he believed U.S. differences with Ukraine could be reconciled.
