Sen. Chris Van Hollen (D-MD) endorsed leftist Democrat Abdul el Sayed in his run to replace retiring Sen. Gary Peters (D-MI) in Michigan.

Van Hollen is now the second sitting senator, behind Sen. Bernie Sanders (I-VT), to back el Sayed’s bid for the seat over more centrist candidates Rep. Haley Stevens (D-MI) and state Sen. Mallory McMorrow. Stevens is seen as the more establishment candidate, boasting an effective endorsement from Senate Minority Leader Chuck Schumer (D-NY).
