Hunter and his wife entered pleas of not guilty on Thursday after the Justice Department charged the two this week with using campaign funds for personal expenditures, including a family trip to Italy.

Their next court appearance is scheduled for Sept. 4, according to local news reports, and the California lawmaker's bail was set at $15,000.

As he left the courtroom, the congressman was followed closely by protesters as demonstrators chanted "shame!" and "shame on you" at Hunter, who was obscured from cameras by protest signs including signs supporting his Democratic challenger, Ammar Campa-Najjar.
