Nigerian national Umar Farouk Abdulmutallab, 24, also fired his court-appointed attorneys, saying they weren't representing his best interests, the reports said. He will now represent himself.
"In my opinion, you would be far better defended by a trained lawyer then by yourself," Edmunds told Abdulmutallab.
"They have worked on what they believe is in my best interest," Abdulmutallab said of his legal team, according to The Detroit News. "But not what I believe is in my best interest."
At one point, Abdulmutallab indicated he might be considering pleading guilty to some charges and asked the judge, "If I want to plead guilty to some counts, how would that work?" She said she couldn't offer him legal advice, according to the Free Press.
Abdulmutallab is charged with attempting to murder nearly 300 people on Northwest Airlines Flight 253 on Christmas Day. Authorities say he tried to ignite an explosive device in his pants, but it only created smoke before fellow passengers tackled him. Investigators have alleged that Abdulmutallab was an al-Qaida operative trained in Yemen.
His court appearance was accompanied by heavy security at the courthouse that included bomb-sniffing dogs and federal agents from the Department of Homeland Security, The Detroit News reported.
Lawyers had been expected today to discuss pretrial issues and possibly get a trial date, but no date was set.
Authorities have said Abdulmutallab has been been cooperating with them. He may not have a lot of bargaining room, considering they say he was caught with a "smoking gun" -- or in this case, a smoking explosive.
