WASHINGTON -- The official in charge of exposing wrongdoing inside the troubled Homeland Security Department has been transferred amid allegations that he abused his position, officials said Tuesday.
Charles K. Edwards was scheduled to appear before a Senate panel on Thursday to answer questions about allegations that he improperly employed his wife, misused travel funds and covered up details about a Secret Service prostitution scandal. He has denied any wrongdoing.
The Senate hearing was canceled after he left his post.
Edwards, a career civil servant, was the department's deputy inspector general. But he had run the office since February 2011 because the White House had not nominated a new inspector general.
At his request, Edwards was reassigned to the department’s science and technology directorate, the research and development arm, officials said.
Senate investigators have been looking into allegations that Edwards held back details from reports about U.S. Secret Service agents who hired prostitutes in Cartagena, Colombia, while planning a presidential visit to the country in 2012.
