Apologizing for "intimidating conduct," embattled San Diego Mayor Bob Filner (D) on Friday said he plans to enter a "behavior counseling clinic" for two weeks of therapy beginning Aug. 5. But he vowed to remain in office, even as he faced a flurry of calls to step aside from top Democrats, amid allegations he sexually harassed multiple women.

Filner said he plans to "undergo two weeks of intensive therapy to begin the process of addressing my behavior." He said the treatment will be "the first step" in a longer process "that will involve ongoing regular counseling."

"I must become a better person," Filner said.
