Former Rep. Ken Buck blasted Rep. Marjorie Taylor Greene (R-GA) for her stance against sending aid to Ukraine amid its war against Russia.

Buck appeared Friday evening on Erin Burnett OutFront, less than a day before the House voted on and eventually passed the Ukraine Security Supplemental Appropriations Act, allocating $60.84 billion to the effort. Greene voted against the measure and referred to the vote as a “betrayal” on Speaker Mike Johnson’s (R-LA) part.
