The Hill reports that several Republican members of Congress are demanding an investigation into allegations that the Council on American Islamic Relations tried to plant “spies” in the national security apparatus:

Republican members of the Congressional Anti-Terrorism Caucus say the Council on American Islamic Relations (CAIR), tried to plant “spies” within key national security committees to shape legislative policy in its favor.

Reps. Sue Myrick (R-N.C.), John Shadegg (R-Ariz.), Paul Broun (R-Ga.) and Trent Franks (R-Ariz.), citing the recently released book Muslim Mafia: Inside the Secret Underworld that’s Conspiring to Islamize America, called for the House sergeant at arms to investigate whether CAIR had been successful in placing interns on key committees. The lawmakers are specifically focused on the House Homeland Security Committee, Intelligence Committee and Judiciary Committee.

“If an organization is connected to or supports terrorists [and] is running influence operations or planting spies in key national security-related offices I think this needs to be made known,” Broun said. “So I join my colleagues here today in calling for action.”

The book, which was written by P. David Gaubatz and Paul Sperry with a forward by Myrick, is scheduled to be released Thursday.
