Third District Congressman John Yarmuth has been appointed to the House Oversight and Government Reform Committee.The high-profile post places Yarmuth across the table from California Republican Darrell Issa, who chairs the committee. Issa has said he intends to use the committee's power to conduct hundreds of interviews and investigate the Obama administration.Issa has been asked to back off from his aggressive stance, and Yarmuth says he wants to stop any potential witch hunts in Congress."It remains to be seen how aggressive he'll be. We want aggressive oversight of all activities of government. That's important. But you don't just go issuing thousands and thousands hoping you're going to uncover something. You have to have a reason for an investigation," he says. "When you have a chairman who has gone on the record and said publicly that he thinks the Obama administration is the most corrupt administration in history and that he plans to aggressively pursue investigations. That, to me, reeks of witch hunt potential."Yarmuth will serve on subcommittees on national security and financial services. The first full committee meeting is next Wednesday. The panel will discuss the Troubled Asset Relief Plan, also known as the bailout. Yarmuth previously served on the Ways and Means Committee, but lost his seat when the GOP gained the majority
