A Minnesota National Guard veteran facing federal fraud charges made an appearance in court Monday, and the judge ruled that he will remain in custody while awaiting trial. 25-year-old Keith Novak is accused of stealing security clearance information, Social Security numbers and the names of 400 people in his former Army unit. Federal prosecutors accuse him of running a militia, and say he would steal the personal information to make fake ID cards for militia members. The judge in the case deemed Novak a flight risk, and rejected a request to release him. The FBI says that he had resisted arrest and threatened to kill anyone who arrested him. The case is now being referred to a grand jury.
