Democratic Michigan state Sen. Mallory McMorrow on Wednesday criticized Rep. Haley Stevens (D-MI) for her impeachment inquiry of Health and Human Services Secretary Robert F. Kennedy Jr.

McMorrow said her U.S. Senate primary opponent indulged in “political theater” with the move, which is unlikely to gain traction. Stevens, McMorrow, and progressive physician Abdul El-Sayed are in a three-way race to capture the Democratic Senate nomination in Michigan.
