(ABC) The U.S. Capitol’s overnight custodial staff allege they were sexually harassed, exposed to pornography in lawmakers’ offices and overheard conversations in which others were being harassed, according to a watchdog investigation into 10 years of sexual harassment reports in the Architect of the Capitol, the office responsible for maintenance and operations on Capitol Hill.

In a report submitted to Congress by the Office of the Inspector General, Architect of the Capitol staff said they often do not speak up about inappropriate behavior for fear of retaliation. One staffer reported no one had an answer for them when they asked during sexual harassment prevention training, “what happens if the harasser is a member of Congress?”

The report doesn’t specify how many complaints about lawmakers were filed.
