A top FBI official struggled on Thursday to answer basic questions about antifa, a loosely organized collective of anti-fascist activists that he labeled the top terrorist threat facing the US.

Michael Glasheen, operations director of the FBI’s National Security Branch, testified before the US House Committee on Homeland Security that antifa was “the most immediate violent threat” facing Americans today when it comes to domestic terrorism.

But when Rep. Bennie Thompson (D-Miss.), ranking member of the Homeland Security Committee, asked Glasheen for specifics about this purportedly dire threat, he mostly came up empty.

“So where is antifa headquarters?” Thompson asked him.

Glasheen paused for several seconds and then said, “What we’re doing right now with the organization...” before Thompson interrupted him.

“Where in the United States does antifa exist?” asked Thompson.

“We are building out the infrastructure right now,” Glasheen replied.

“So what does that mean?” asked a bewildered Thompson. “I’m just, we’re trying to get information. You said antifa is a terrorist organization. Tell us, as a committee, how did you come to that? Whether they exist, how many members do they have in the United States as of right now?”

“Well, that’s very fluid,” Glasheen said. “It’s ongoing for us to understand that... no different from al-Qaeda and ISIS.”

Thompson again interrupted and tried to make Glasheen answer his original question.

“If you said antifa is the No. 1 domestic terrorist organization operating in the United States,” he said, “I just need to know where they are, how many people. I don’t want a name, I don’t want anything like that. Just, how many people have you identified, with the FBI, that antifa is made of?”

“Well, the investigations are active...” Glasheen said.

Thompson then became incredulous.

“Sir, you wouldn’t come to this committee and say something you can’t prove,” he said. “I know you wouldn’t do that. But you did.”

Many observers were stunned that Glasheen appeared to know so little about what he proclaimed to be the top domestic terrorist threat facing the US.

“Total amateur hour in US law enforcement,” remarked Democracy Docket news editor Matthew Kupfer, “where the No. 1 terror threat is an organization that does not formally exist and a career FBI official is dancing around before a congressional committee trying to make the Trump strategy sound legit.”

Zeteo editor-in-chief Mehdi Hasan argued that Glasheen’s testimony was proof that the administration was simply concocting domestic terrorism threats with zero basis in reality.

“Wow,” Hasan marveled. “Just a complete admission here that the entire ‘antifa’ threat narrative is totally manufactured by this administration.”

Fred Wellman, a Democratic congressional candidate in Missouri, wondered how many actual dangerous criminals are running free while the FBI focuses on taking down an organization that it apparently knows nothing about.

“This would be comical if there wasn’t real world impact from this idiocy,” Wellman wrote. “We have real crimes and real threats and they are chasing a fake ‘organization’ for politics.”

Democrats on the House Homeland Security Committee also piled on Glasheen, citing his testimony as evidence that the Trump administration is completely unserious about law enforcement.

“If your ‘top threat’ has no headquarters, no organization, and no definition then it’s not a top threat,” they posted on social media. “The Trump administration is ignoring real threats, and the American people see right through it.”
