CAIR sued P. David Gaubatz and his son Chris Gaubatz in federal court last month, claiming it was the victim of theft and trespassing.
In the book, Muslim Mafia: Inside the Secret Underworld That's Conspiring to Islamize America, the Gaubatzes acknowledge that Chris adopted a pseudonym and posed as a Muslim convert to secure an internship at CAIR in 2008.
He used his access to take thousands of pages of internal CAIR documents and to make surreptitious recordings of CAIR officials. Citing those records, the book claims that CAIR is part of a conspiracy among groups affiliated with the Muslim Brotherhood "to support violent jihad and undermine law enforcement."
Among the book's specific allegations, CAIR officials grossly exaggerate their membership rolls and the depth of their domestic financial support. In addition, they actively thwart law enforcement counter-terror investigations. Following the release of the book, four congressional Republicans sought an investigation into the book's claims that CAIR seeks to place interns on committees dealing with the judiciary and homeland security.
Thus far, CAIR has minimized and ridiculed the book's findings, but has not alleged any of it is false.
CAIR won a temporary restraining order requiring that the Gaubatzes return 12,000 pages of documents.
WorldNetDaily, publisher of Muslim Mafia, posted a story Nov. 24 claiming that FBI agents served a grand jury subpoena on the Gaubatzes' attorney. The move came as the attorneys were about to comply with the judge's order and give the documents back to CAIR. WND publisher Joseph Farah is quoted saying they weren't sure "Which takes precedence - a federal court order or an FBI warrant?"
