Donald Trump has said that Joe Biden's pardons of members of Congress who investigated the January 6 insurrection are "void, vacant and of no further effect."

US President Donald Trump said his predecessor’s 11th-hour pardons of members of Congress who investigated the January 6 insurrection were “void, vacant and of no further force or effect,” signaling his administration may attempt to upend more than a century of law and practice for presidential pardons.

President Trump questioned who was running the country the last four years following a scathing report claiming former President Joe Biden used "autopen signatures" on important documents.
