Connie Mack becomes the 30th congressman to call for Holder’s resignation

Attorney General Eric Holder’s service in the Obama administration may be coming to an end. Thirty members of Congress are now calling for Holder’s immediate resignation — a number that grows larger every day.

Florida Republican Rep. Connie Mack became the latest congressman to demand that Holder step down, telling The Daily Caller late on Tuesday that “Eric Holder should resign Fast and Furiously!”

Mack is a high-profile political figure who entered Florida’s Republican primary for Senate last week. Mack’s decision to call for Holder to resign appears to signal that it’s politically popular.

Also, Mack’s wife, California Republican Rep. Mary Bono Mack, previously told the TheDC that she’s deeply concerned about Holder’s behavior throughout the investigation into Operation Fast and Furious.

“Congresswoman Bono Mack is deeply concerned about ‘Fast and Furious’ and certainly a resignation is not out of the question,” her spokesman Cort Bush told TheDC earlier this week.

North Carolina Rep. Walter Jones tweeted on Tuesday afternoon,”It’s time for Eric Holder to go!” He joined 28 other members who had called for Holder to resign by Tuesday morning.

The Justice Department and President Barack Obama’s White House haven’t answered any of TheDC’s requests for comment about the growing contingent of congressmen calling for Holder to immediately remove himself from office.

The administration’s continued failure to defend Holder suggests that the president may be keeping the door open to pushing Holder out of office to prevent the scandal from seeping into campaign season.

Three presidential candidates — Rep. Michele Bachmann, former Pennsylvania Sen. Rick Santorum and former Massachusetts Gov. Mitt Romney — have made, in one form or another, a call for Holder’s resignation.

Although only Republicans have called for Holder to resign thus far, one Democrat told TheDC that he wants the investigation to plow forward and figure out what Holder knew and when he knew it.

“There needs to be much more investigation by the Administration and/or Congress on how this program started and what if any oversight by the Attorney General,” Texas Democratic Rep. Gene Green told TheDC. “It is absolutely critical that our nation’s leading officials be honest in their testimony before Congress. I hope the Justice Department and Congress will continue to look into these very serious charges to uphold the integrity of our system.”

The continued congressional pressure on Holder comes as the Attorney General’s top deputy, Assistant Attorney General Lanny Breuer, testified before a Senate Judiciary Committee hearing on Tuesday. At the hearing, ranking Republican member Sen. Chuck Grassley of Iowa pushed Breuer on his recent claims that he was responsible — at least partially — for not informing Holder that gun walking tactics were used during the Operation Fast and Furious.

Gun-walking is when the Bureau of Alcohol, Tobacco, Firearms and Explosives allows straw purchasers to take guns across the border without stopping them, even when law enforcement agents have the chance to do so. Straw purchasers are people who can legally purchase weapons in the United States but do so with the known intention of trafficking them into Mexico.
