By ALANNA DURKIN RICHER, ERIC TUCKER and COLLEEN LONG WASHINGTON (AP) — During hearings on Merrick Garland’s nomination to be President Joe Biden’s attorney general, the longtime federal appeals court judge told senators in 2021 that he hoped to “turn down the volume” on the public discourse about the Justice Department and return to the days when the agency was not the “center of partisan disagreement.” It didn’t go as planned. Garland came in with a mission to calm the waters and restore the department’s reputation for independence after four turbulent years under Republican President Donald Trump, who fired one attorney general and feuded with another.
