White House aide Sebastian Gorka’s involvement in the trial of Boston Marathon bomber Dzokhar Tsarnaev was more limited than his professional biography indicates, according to a Friday report from Fusion.

Gorka, a self-proclaimed expert on counterterrorism with hardline views on Islam who was once arrested for attempting to carry a gun through airport security, has long sold himself as an “expert witness” on the trial. His LinkedIn bio claims that he spent 11 months as an “expert” for the U.S. Attorney in Massachusetts consulting on the trial, and he noted it in his biographies for the Washington Speakers Bureau and for multiple other professional speaking engagements.

Gorka did submit a lengthy “expert report” on the “global Jihadist movement” to the U.S. attorney’s office, but an anonymous official at the U.S. attorney’s office in Boston told Fusion that Gorka never testified at the trial.

“He was certainly on the list of potential witnesses,” the official told Fusion. “But he was never called, nothing he gave us was ever used.”
