Democrat Karen Bass marked the end of her tenure as speaker of the California Assembly Tuesday by promptly transitioning into her campaign for Congress. "As soon as I walk away from the speakership, I will be running fast and furious" for Rep. Diane Watson's (D) House seat, Bass told reporters.

Bass used her final press conference as speaker to reflect on her two-year term.

"It was definitely the two most difficult years that I've ever experienced politically ... but I was glad I was there," she said.

Bass' campaign for the Democratic nod in Watson's district is gaining momentum -- EMILY's List announced Tuesday it's backing her

As the first African-American woman elected to the position, EMILY’s List President Stephanie Schriock said in a statement, “Karen has been an innovative Speaker of the Assembly in California. In the legislature, Karen has been a champion for better schools and health care reform.”

Bass faces Democrat Mervin Evans and Deputy Los Angeles City Atty. Felton Newell in the June 8 primary.
