From The Washington Times:

The embattled inspector general at the Department of Homeland Security was the target of a number of internal employee complaints for abuse of power before his surprise decision to step down earlier this week, according to new documents shown to The Washington Times by an outside watchdog group. Acting Inspector General Charles Edwards asked for reassignment to another agency post Tuesday, facing allegations of misconduct and questions about his willingness to work with Congress. He has denied any wrongdoing, and no reason was given for the move.
