Rep. Alexandria Ocasio-Cortez (D-N.Y.) said Rep. Haley Stevens (D-Mich.) has “been with the Republicans” since Congress returned, after the Michigan Democrat endorsed former Rep. Mike Rogers (R-Mich.) in the midterms.

“She’s been with the Republicans ever since she’s come back. So she’s been on the Republican side of the aisle,” Ocasio-Cortez said during an appearance on “The Don Lemon Show” that aired Thursday.

“This is just the epitome of a certain kind of transactional politics,” she added. “And it’s really sad.”
