Failed airline bomber Umar Farouk Abdulmutalla has dismissed his legal team and will represent himself in court in Detroit today.
The 24-year-old Nigerian, who tried to blow up a flight from Amsterdam to the city last Christmas Day, is due for a pre-trial hearing.
He will be accompanied by a standby lawyer who can give advice.
Last month Abdulmutalla suggested he wanted to plead guilty to some charges.
He is charged with attempting to use a weapon of mass destruction to blow up Northwest Airlines Flight 253 by trying to fire to explosives hidden in his underwear.
He has been held at a federal prison in Michigan since his arrest.
