Seattle City Councilmember Teresa Mosqueda was sworn into office Tuesday at City Hall.

“We are leading the nation, because our community is coming together and it is an incredible honor to be joining this team,” Mosqueda said.

Mosqueda took office earlier than previous councilmembers to fill the seat. Position No. 8 was held by Tim Burgess, who vacated his seat in September to serve as interim mayor.

Mosqueda’s election also moves the Council to a female supermajority.

A labor leader, Mosqueda has said her priorities will be around protecting working families, seniors and the most vulnerable.
