Rep. Darrell Issa (R-CA) says the House Oversight and Government Reform Committee is finally “beginning to break down the walls of silence and refusal” from the Obama administration about the Operation Fast and Furious scandal. As its chairman, Issa has doggedly pursued answers on the illegal gun trafficking operation run by the Bureau of Alcohol, Tobacco, Firearms and Explosives.

This week on Scribecast, we spoke to Issa about Operation Fast and Furious, his investigation of President Obama’s questionable fundraising activities at the White House, and his plan for reforming the U.S. Postal Service.

Listen to our interview with Rep. Darrell Issa on this week’s Scribecast

Since taking over as Oversight and Government Reform chairman in January, Issa’s committee has embarked on a number of investigations and held hearings on a range of policy issues. It played an instrumental role in the formation of American Job Creators and has worked in a bipartisan spirit on legislation such as the Digital Accountability and Transparency Act of 2011.

But most headlines of late have focused on Operation Fast and Furious and the use of the White House for political fundraising. In our interview, Issa explained the ramifications of both and why he’s asking tough questions of the Obama administration.
