The man accused of breaking into U.S. House Speaker Nancy Pelosi's San Francisco home and clubbing her husband in the head with a hammer pleaded not guilty on Tuesday to attempted murder and other charges and was ordered to remain jailed without bond.

David Wayne DePape, 42, showed up for his first court appearance since Friday's attack with his right arm in a sling, a consequence, his court-appointed public defender said, of a dislocated shoulder suffered during the arrest.

The attorney, Adam Lipson, told reporters afterward that DePape's legal team would review a number of issues that might factor into his client's defense, including his "vulnerability" to "political misinformation" and his mental state.
