WASHINGTON (AP) - D.C. Councilmember Muriel Bowser will announce her candidacy for mayor in front of her childhood home in northeast Washington.

The announcement is scheduled for 11 a.m. Saturday.

The 40-year-old Bowser has been on the council since 2007. A Democrat, she won a special election to replace Adrian Fenty after he was elected mayor.

Bowser has been a frequent critic of Mayor Vincent Gray, saying the city needs a leader with energy and vision. She was one of three councilmembers to call for Gray's resignation last summer amid revelations that he was elected with the aid of $650,000 in illicit funds.

Gray's 2010 campaign remains under investigation, and he has not said whether he is running for re-election or given a timetable for a decision.
