Voters in Jefferson County, Colo., are petitioning to recall three conservative members of the local school board who caused a national stir last fall after criticizing the Advanced Placement U.S. History course for being insufficiently patriotic.

Residents collected more than twice the number of required signatures on a petition to recall the three conservative members of the five-member Jefferson County Board of Education.

Jeffco United for Action said it had more than 110,000 on petitions to recall board members John Newkirk, Ken Witt and Julie Williams. The group needs 15,000 valid signatures for each board member it wants to unseat in order to force a recall election.
