Biden inauguration: 25,000 National Guard vetted over insider attack fears as state protests fizzle

FBI conducting vast security sweep as Sunday's protests see law enforcement and media outnumber members of Boogaloo Bois'

The FBI is vetting all 25,000 National Guard troops arriving in Washington DC for president-elect Joe Biden's inauguration amid fears of an insider attack, as heavily fortified state capitals across the US saw only small-scale protests by far-right groups on Sunday.

Commanders have been warned to be on the lookout for problems within their ranks, and Guard members are being trained to identify potential insider threats, army secretary Ryan McCarthy told the Associated Press.
