Curtis Wayne Allen, one of three men charged in the Garden City bombing plot, waived his detention hearing on Monday.
He also pleaded not guilty to federal charges that he and two other men conspired to use a weapon of mass destruction at a Garden City apartment complex where about 120 people live, including Somali immigrants who are Muslims.
Allen remains in federal custody pending trial. Allen appeared before Magistrate Judge Gwynne E. Birzer on Monday. He was arrested on Oct. 14 in Liberal by FBI agents.
Prosecutors say Allen and co-defendants Gavin Wright and Patrick Stein were part of an anti-Muslim militia group called the Crusaders. The FBI says the men planned to detonate vehicles laden with explosive materials around the complex, which has at least one room that is being used as a mosque, on Nov. 9, the day after the general election.
