MANCHESTER, N.H. — Rep. Pramila Jayapal, a rising star in the Democratic Party's liberal wing and one of the most prominent women of color in Congress, is endorsing Sen. Bernie Sanders for president, choosing him over Sen. Elizabeth Warren on the heels of an explosive confrontation over the question of whether a woman can defeat President Trump.

In a telephone interview with The Washington Post on Sunday, Jayapal (D-Wash.) said she decided to endorse Sanders because "he has a clarity on policy prescriptions that goes right to the heart of what working people need." She will unveil her endorsement Monday in Iowa.

Jayapal also told The Post she will be named national health policy chair for the Sanders campaign, as well as a Washington State chair.

The endorsement is a significant get for Sanders (I-Vt.) and a blow to Warren (D-Mass.), who has forged a friendship with Jayapal in recent years and is seeking to rally support from women as she makes her closing argument to voters before the first nominating contest in Iowa on Feb. 3.
