Real News From The Blaze:' Fast and Furious Scandal at the White House Doorstep

House Oversight Committee Chairman Darrell Issa is once again poking the White House as a remindier that they are still at the center of his radar amidst the congressional investigation of the ATF gunwalking scandal Operation Fast and Furious. Rep. Issa sent a letter to the White House Monday night demanding answers as to why the president invoked executive privilege over documents requested from the Justice Department for the investigation.

In the letter Rep. Issa accuses that President Obama withheld documents for one of two reasons:

• "Either you or your most senior advisors were involved in managing Operation Fast & Furious and the fallout from it, including the false February 4, 2011 letter provided by the Attorney General to the committee,
• "Or you are asserting a presidential power that you know to be unjustified solely for the purpose of further obstructing a congressional investigation."

Rep. Issa has demanded to see all communications between the White House and the DOJ from Feb 4, 2011 to June 18, 2012, the day before he says the Attorney General requested that President Obama assert executive privilege.

With this going on, The Daily Caller reported Monday that there may be one "smoking-gun" internal Department of Justice email that could document the scandal if it turns out to contain what congressional investigators say it does. The DC reports that the document would allegedly establish that wiretap application documents show senior DOJ officials knew about and approved the gunwalking tactic in the operation.

On Thursday, the full House is expected to vote whether to hold Attorney General Eric Holder in contempt of Congress for refusing to turn over internal documents related to the Justice Department's response to the Fast and Furious investigation.

What sort of damning scenario could potentially be out there if the administration is intentionally holding back investigators from a smoking gun? The "Real News" panel discussed this Tuesday, as well as broke down what Rep.Issa is hoping to achieve with this letter. Katie Pavlich, who has already written a bestselling book on Fast and Furious, phoned in to discuss Rep. Issa's action and how far up the scandal could go. Pavlich also broke down how Operation Fast and Furious differs from Operation Wide Receiver. Watch:
