Without citing evidence, Mr. Pierce has said he intends to implicate the F.B.I. and the intelligence community by showing that the riot was something like a grand act of entrapment or an inside job. He has often talked about his cases with a conspiratorial zeal, painting himself as something like a lonely legal warrior out to save his clients from an overreaching government.
“I’m like Gerard Butler in ‘300,’” Mr. Pierce said in an interview before dropping out of sight, comparing himself to the action star who played a Spartan king. “I’m in the hot gates at Thermopylae, holding the pass against the million-man Persian army.”
While the government has not yet weighed in on the merits on his claims, prosecutors did express concern in their letters filed on Monday about the young associate, Ryan Joseph Marshall, who has been standing in for Mr. Pierce at the hearings he has missed.
For one thing, Mr. Marshall is not a licensed lawyer, prosecutors said, and has taken actions on behalf of clients “that he is not permitted” to take. Moreover, they went on, it remains unclear if and when Mr. Marshall will be able to get his law license given that he is under indictment in two criminal cases accusing him of corruption, theft and fraud in Pennsylvania.
