Jacob Chansley, also known as the "QAnon shaman," was arrested for his part in the Jan. 6 riot. His attorney, Al Watkins, said Chansley would be willing to testify to Congress that former President Donald Trump incited him to break through law enforcement barriers and raid the Capitol.
Graham, a South Carolina Republican and one of Trump’s biggest Capitol Hill allies, tore into the idea of having Chansley back on the Senate floor for impeachment, arguing that doing so would obliterate the solemnity of the proceedings.
