Merrick Garland, President Biden’s nominee for attorney general, is appearing before the Senate Judiciary Committee today — nearly five years after Senate Republicans refused to hold hearings for Garland to become a justice on the Supreme Court. Garland is expected to tell lawmakers he will oversee the prosecution of white supremacists responsible for the January 6 insurrection on the U.S. Capitol. The first congressional hearings on the insurrection begin this week.
