Thursday marks the date when some right-wing conspiracy theorists have claimed that former President Donald Trump, who was defeated in the November 3 election, will be sworn in for a second term in office.

The Capitol Police statement noted that it already has made "significant security upgrades" at the Capitol, home to the US House of Representatives and Senate.
It was unclear if these upgrades were done in response to this latest threat or whether it includes the measures already in place following the January 6 riot.
