In an O'Reilly Factor investigation Thursday night, we heard about another Illinois professor with past links to U.S. domestic terror groups. James Kilgore, an art teacher at the University of Illinois, was once part of the radical Symbionese Liberation Army, which carried out a string of bank robberies in the 1970s, as well as the kidnapping of newspaper heiress Patricia Hearst

Kilgore had been arrested on-the-run in South Africa in 2002, extradited to the United States, and served a six-year sentence for the murder of a Sacramento, Calif. woman.

Laura Ingraham said the situation is similar to Bill Ayers, the former Illinois-Chicago professor who co-founded the radical Weather Underground group in the 1960s. Ayers made national headlines in 2008 over his prior contacts with then-presidential candidate Barack Obama.

Illinois State Sen. Chapin Rose (R) joined Ingraham to discuss the situation. Rose supports the effort by Chris Kennedy, the university's Board of Trustees chairman, to have Kilgore removed from his position. But Ingraham noted that many of Kilgore's fellow professors are supporting him, citing academic freedom.

Watch the full discussion above, and tune in Monday at 8/11p ET - Bill's back with a new "Watters' World," Brit Hume and Bernie Goldberg.
