US Law Enforcement Authorities Step Up Investigation of Capitol Hill Riots Masood Farivar U.S. law enforcement authorities are stepping up a criminal investigation into Wednesday's attack on the U.S. Capitol by supporters of President Donald Trump that could include his role in instigating the mob. Acting U.S. Attorney for the District of Columbia Michael Sherwin said a total of 55 people have been charged with various crimes, including 15 people in connection with rioting at the Capitol. Trump has been widely condemned for inciting the violence by imploring supporters angry over his electoral loss to march on the Capitol. In a rare rebuke, former Attorney General William Barr, a staunch Trump ally while in office, said in a statement that the president's conduct "was a betrayal to his office and supporters." .
