Thursday is March 4 - the date followers of QAnon falsely believe Donald Trump will reclaim the presidency.
QAnon adherents,who ascribe to a baseless theory that Trump is on a secret mission to expose a Satanist cabal of Democratic paedophile politicians,picked March 4 because it was the original date for presidential inaugurations until 1933.
With the deadly January 6 attack on the Capitol still fresh on their minds,House leaders cancelled votes planned for Thursday and advised members they did not need to appear.
The Senate,which is working on the coronavirus stimulus package,has not cancelled its Thursday session.
Capitol Police vowed to beef up security on Thursday.
House Sergeant-at-Arms Timothy Blodgett also issued a memo warning that there could be trouble into the weekend,with “additional interest in the Capitol for the dates of March 4th-6th by a militia group”.
