Teresa Mosqueda picked up the endorsement of Seattle City Council Member Mike O'Brien today, giving her support from a majority of the council in her race for an open citywide seat.

"Teresa is an organizer who has stood against powerful interests and won," O'Brien said in a statement released by Mosqueda's campaign today. "Throughout her career, Teresa has fought for workers and low-income communities in Washington State."

In the statement, O'Brien cited Mosqueda's opposition to a new youth jail and her criticism of homeless encampment sweeps and described her as a "strong champion for workers' rights."

O'Brien, who last week endorsed Nikkita Oliver for mayor, is the fifth council member to get behind Mosqueda. He joins Sally Bagshaw, Rob Johnson, Debora Juarez, and Lorena González. Council Members Kshama Sawant and Lisa Herbold—often allies of O'Brien—have endorsed Mosqueda's most viable opponent, Jon Grant. Council Member Bruce Harrell has not endorsed in the race. Council Member Tim Burgess, whose retirement is leaving this seat open, has said he won't endorse until after the primary.
