Former Los Angeles Mayor Antonio Villaraigosa won't run for the U.S. Senate seat being vacated by retiring Sen. Barbara Boxer (D-CA), likely paving the way for California Secretary of State Kamala Harris (D) to win the heavily Democratic state in 2016.

Villaraigosa tweeted, "I've decided not to run for US Senate, my heart and family are in CA. But our work is not done and neither am I."

In a statement, he added that he's "humbled" by the support he received from those who encouraged him to run.

"I have decided not to run for the U.S. Senate and instead continue my efforts to make California a better place to live, work and raise a family," he said.

That Villaraigosa tweet leaves open the possibility he might run for CA GOV in 2018, but he's passing on a 2016 Senate bid.
