The man who clubbed U.S. House Speaker Nancy Pelosi's husband in the head with hammer, shouting "Where is Nancy?" after forcing his way into the couple's San Francisco home, faced charges of attempted murder and other felonies a day later.

Police have not offered a motive for Friday's assault on Paul Pelosi, 82, who according to his wife's office underwent surgery for a skull fracture and injuries to his hands and right arm, though doctors expect a full recovery.
