A lawsuit filed Monday by an Islamic civil rights group on behalf of Khairullah and other plaintiffs says his exclusion from the White House event demonstrates that Muslims face negative repercussions even after they are able to clear their name from the list. The Secret Service declined to comment on the lawsuit. The FBI's Terrorist Screening Center plays a primary role in the watchlist, though many government agencies are involved in the secretive process. CAIR contends that its lawsuits have uncovered the breadth of government agencies that use the list, from local law enforcement to the State Department to the Secret Service. That's because in most cases, the government refuses to tell people if they've been placed on the list or if they've been removed.
