U.S. defense officials say the federal government is conducting insider-threat screening on the 25,000 National Guard troops who have begun flowing into the nation’s capital to secure the inauguration, as concerns intensify about extremism in the ranks.
The extra precaution comes after a number of pro-Trump rioters involved in storming the U.S. Capitol on Jan. 6 turned out to have military ties, raising questions about extremist sentiment within the armed forces. Dozens of people on a terrorist watch list were in Washington as the deadly riot unfolded.
A U.S. defense official, speaking on the condition of anonymity to discuss the sensitive preparations, said the Army is working with the FBI to vet all service members supporting the inauguration. The Army maintains awareness of threats but does not collect domestic intelligence itself, the official said. It was not immediately clear how extensive the FBI vetting of the military personnel would be.
