While Attorney General Eric Holder is already facing intense pressure from House Republicans in regard to the investigation of Operation Fast & Furious, GOP members in the Senate have begun to up scrutiny for the investigation of continued national security leaks from the Obama administration. Thirty-one Republican senators signed a letter sent to Holder Tuesday, demanding that a special prosecutor be assigned to investigate ”an avalanche of leaks” on national security matters, rather than the two US attorneys assigned now for the criminal investigation.

The demands come as a new book from David Sanger, Confront and Conceal: Obama’s Secret Wars and Surprising Use of American Power, appears to reveal details linking the leaks to current National Security Advisor Thomas Donilon. His name came under suspicion as a result of David Sanger’s new book  about the Obama Administration’s foreign policy. An excerpt from the book posted by ABC’s Jake Tapper shows the tension between Donilon and the Pentagon as details from the raid on Osama bin Laden began to permeate in the media shortly after the event:

“At the Pentagon, top officers fumed at Brennan’s blow-by-blow description of how the SEALs operated; they believed that the former CIA officer had given away operational secrets never shared outside the tribe. (In fact, it appears no real secrets were divulged.) No one was angrier than Mullen himself, who still fumed about that news conference nearly a year later…

“By Wednesday of that week, Gates went to see Donilon, offering up a barbed assessment of how the White House had handled the aftermath of the raid.

“‘I have a new strategic communications approach to recommend,’ Gates said in his trademark droll tones, according to an account later provided by his colleagues.

“What was that, Donilon asked?

“‘Shut the f@*k up,’ the defense secretary said.”

The panel on “Real News” Wednesday discussed the leaks investigation and how this latest scandal may increase public focus and frustration towards the Justice Department and administration as a whole:
