Twitter, assailed by some critics as hostile to conservative voices, has apparently imposed a ban on those seeking to audit 2020 presidential election results, including some involved in the first-of-its-kind forensic audit in Maricopa County, Arizona.

Reports first noted the banning of two accounts sharing information from the Arizona forensic audit, but accounts sharing information on audit intentions in other states were suspended by Twitter on Tuesday afternoon, according to multiple reports.

The accounts included those designed to inform about the Georgia, Wisconsin, Nevada, and Pennsylvania audits, too. Those are among the states that decided the election for President Joe Biden and the bans come on the day House Speaker Nancy Pelosi’s Jan. 6 Select Committee began hearing from law enforcement officers who were beaten during the storming of the Capitol.
