Fearing insider attack, FBI vetting 25,000 National Guard troops for Joe Biden inauguration
- Massive undertaking reflects fears that have gripped Washington following the deadly January 6 insurrection
- Joe Biden to be sworn in as US president on Wednesday, surrounded by war-zone-like security

US defence officials say they are worried about an insider attack or other threat from service members involved in securing President-elect Joe Biden’s inauguration, prompting the FBI to vet all of the 25,000 National Guard troops coming into Washington for the event.
The massive undertaking reflects the extraordinary security concerns that have gripped Washington following the deadly January 6 insurrection at the US Capitol by pro-Trump rioters. And it underscores fears that some of the very people assigned to protect the city over the next several days could present a threat to the incoming president and other VIPs in attendance.
Army Secretary Ryan McCarthy said that officials were conscious of the potential threat, and he warned commanders to be on the lookout for any problems within their ranks as the inauguration approaches. So far, however, he and other leaders say they have seen no evidence of any threats, and officials said the vetting hadn’t flagged any issues.
“We’re continually going through the process, and taking second, third looks at every one of the individuals assigned to this operation,” McCarthy said in an interview after he and other military leaders went through an exhaustive, three-hour security drill in preparation for Wednesday’s inauguration. He said Guard members were also getting training on how to identify potential insider threats.

About 25,000 members of the National Guard were streaming into Washington from across the country - at least two and a half times the number for previous inaugurals. And while the military routinely reviews service members for extremist connections, the FBI screening is in addition to any previous monitoring.
Multiple officials said the process began as the first Guard troops began deploying to Washington more than a week ago. And they said it is slated to be complete by Wednesday. Several officials discussed military planning on condition of anonymity.
“The question is, is that all of them? Are there others?” said McCarthy. “We need to be conscious of it and we need to put all of the mechanisms in place to thoroughly vet these men and women who would support any operations like this.”
In a situation like this one, FBI vetting would involve running peoples’ names through databases and watch lists maintained by the bureau to see if anything alarming comes up. That could include involvement in prior investigations or terrorism-related concerns, said David Gomez, a former FBI national security supervisor in Seattle.
