The Homeland Security Department official investigating President Barack Obama's nominee to become the department's second-highest ranking official has left his post. He is transferring to another office in the department.
Charles K. Edwards was the acting inspector general. He most recently headed a probe of Alejandro Mayorkas, the Citizenship and Immigration Services director whom Obama wants to become deputy secretary. Mayorkas was accused of improperly influencing decisions in a foreign investor visa program. He has said he did nothing wrong.
Edwards himself was accused of wrongdoing. A Senate subcommittee was investigating claims that Edwards was susceptible to political pressure, engaged in nepotism and abused his authority in other ways. Edwards also has denied he did these things.
The department said Edwards requested the job change last week.
