SAN DIEGO (AP) — San Diego City Hall has opened but there is no sign of the mayor as he faces sexual harassment allegations.

City Council President Todd Gloria says he doesn't know if Mayor Bob Filner will be at City Hall, despite his vow to return to work Monday after undergoing therapy.

Gloria says Filner is not obligated to make an appearance but owes the people of San Diego an explanation of his whereabouts.

Filner has not made his schedule public. His spokeswoman and lawyers did not respond to calls.

Multiple accusations of sexual harassment by Filner have prompted an avalanche of calls for him to resign.

A recall campaign kicked off in earnest on Sunday, and if he does go back to work, Filner faces an uphill battle to prove he can still govern.
