Following John McCain’s condemnation of Michele Bachmann’s letter to the Department of State’s Inspector General, demanding an investigation of imagined ties of Hillary Clinton aide Huma Abedin to the Muslim Brotherhood, other Republicans are piling on.

GOP strategist Ed Rollins, who at one time managed Bachmann’s failed presidential campaign, weighed in at Fox News:

Having worked for Congressman Bachmann’s campaign for president, I am fully aware that she sometimes has difficulty with her facts, but this is downright vicious and reaches the late Senator Joe McCarthy level… The Republican Party, which John McCain led as our nominee in 2008, is going to become irrelevant if we become the party of intolerance and hate. The party founded by Abraham Lincoln was a party that fought slavery and intolerance at every level. I can assure Mrs. Bachmann, that Ms. Abedin has been thru every top clearance available and would never have been given her position with any questions of her loyalty to this country. As a member of Congress, with a seat on the House Intelligence Committee, Mrs. Bachmann you know better. Shame on you, Michele! You should stand on the floor of the House and apologize to Huma Abedin and to Secretary Clinton and to the millions of hardworking, loyal, Muslim Americans for your wild and unsubstantiated charges. As a devoted Christian, you need to ask forgiveness for this grievous lack of judgment and reckless behavior. (emphasis mine)

House Speaker John Boehner today called Bachmann’s accusations “pretty dangerous.”

This appears to be an important moment of Republicans finally trying to dial back the party’s Islamophobia wing, defending public servants from the wild-eyed imaginings of Frank Gaffney’s protégés. Bachmann and the four other signatories to her letter—Republicans Trent Franks (AZ), Louie Gohmert (TX), Thomas Rooney (FL), and Lynn Westmoreland (GA)—open their argument with one of the central lies of Gaffney’s Islamophobia complex: the US government itself, they write, “has established in federal court that the Muslim Brotherhood’s mission in the United States is ‘destroying the Western Civilization from within’—a practice the Muslim Brothers call ‘civilization jihad.’” As a result, they contend, “the apparent involvement of those with such ties raises serious security concerns that warrant your urgent attention.”

Setting aside the fact that Bachmann et al. rely entirely on Gaffney—who has been dismissed by fellow conservatives as a “crazy bigot”—for their unsubstantiated claim that Abedin has Brotherhood ties, their supposed proof of the Brotherhood’s theocratic ambitions in the United States is a fabrication. For her proof, Bachmann cites an exhibit from the US government’s prosecution in the Holy Land Foundation terror financing case. Here’s what I wrote about that exhibit, and that case, over a year ago:

This claim that the Muslim Brotherhood’s aim is a worldwide theocracy, and that all American Muslim organizations fall into lock-step with it, stems solely from a single 20-year-old document written by a single Brotherhood member in 1991. In the controversial terrorism financing trial of the Holy Land Foundation, which first resulted in a mistrial in 2007, and convictions in a 2008 re-trial, federal prosecutors introduced a document, “An Explanatory Memorandum on the General Strategic Goal for the Group in North America.” Gaffney and others have seized upon this document developing theories that the goal of “radical Islamists” is a global theocracy and that the Muslim Brotherhood lurks in every corner of America. GWU’s [Nathan] Brown, who testified in the first Holy Land Foundation trial, said, “Nobody has ever produced any evidence that the document was more than something produced by the daydream of one enthusiast.” Noting that he has been studying Palestinian, Egyptian, Kuwaiti, and Jordanian Brotherhood movements since 2005, Brown added, “Nothing in anything that I have heard has ever struck me as similar in tone or content to the ‘master plan.’” Yet this single document has been used to create a mythology around a supposedly global plot. Brown, addressing the document, notes that “The prosecution in the Holy Land Case painted with a broad brush and probably should not be relied upon. There is indeed a loose coordinating international structure for the Muslim Brotherhood, but it has no real authority over the chapters.” But that hasn’t stopped Gaffney, who said recently, “It is now public knowledge that nearly every major Muslim organization in the United States is actually controlled by the MB or a derivative organization. Consequently, most of the Muslim-American groups of any prominence in America are now known to be, as a matter of fact, hostile to the United States and its Constitution.” Based on the ‘explanatory memorandum’ document identifying a number of American Muslim organizations as allies in its author’s aspirations, prosecutors in the Holy Land Foundation trial publicly labeled over 200 American Muslim organizations “unindicted co-conspirators,” a highly controversial move derided at the time by legal experts as contrary to Justice Department policy and in violation of the groups’ constitutional rights. Eventually, the court ruled, on the motion of three of the groups, including the Islamic Society of North America (ISNA), that publicly identifying them as “unindicted co-conspirators” did violate their Fifth Amendment rights. That didn’t stop The National Review’s Andrew McCarthy—a former federal prosecutor himself—from falsely claiming at CPAC, “those people were all convicted” in the Holy Land Foundation trial.

Meanwhile, the Family Research Council has just appointed Lt. General William G. “Jerry” Boykin (Ret.) as executive vice president. Boykin, among other things, has claimed that “we need to realize that Islam itself is not just a religion—it is a totalitarian way of life. It’s a legal system, shari’ah law; it’s a financial system; it’s a moral code; it’s a political system; it’s a military system. It should not be protected under the First Amendment, particularly given that those following the dictates of the Qur’an are under an obligation to destroy our Constitution and replace it with shari’ah law.” Bachmann is taking heat from fellow Republicans for her attempted witch hunt of Abedin. But will those Republicans back away from the FRC’s Values Voters Summit this fall in protest of Boykin’s history of Islamophobia?
