Rep. Jackie Speier (D) is the third sitting Member to endorse Rep. Janice Hahn in her race against fellow Democratic Rep. Laura Richardson in the redrawn 44th district.

“I’m very proud to strongly back her re-election campaign because I know that she’ll continue to advance the causes that her constituents care about,” Speier said of Hahn, who is heavily favored in the race.

Speier joins Democratic Reps. Grace Napolitano and John Garamendi, as well as former Rep. Diane Watson, in supporting Hahn in one of two Democratic Member-vs.-Member races in Los Angeles County. State Assemblyman Isadore Hall, who dropped out of the race in December, endorsed Hahn on Monday.

Richardson has a long list of Congressional support that primarily includes members of the Congressional Black Caucus.

Hahn and Richardson will face off in the June top-two primary and then again in November.
