By JEFF MARTIN and MICHAEL WARREN ATLANTA (AP) — Americans must commit to the unfinished work of Martin Luther King Jr., delivering jobs and justice and protecting “the sacred right to vote, a right from which all other rights flow,” President Joe Biden said Monday. Martin Luther King Day is a moment when a mirror is held up to America, the president said in a video address. “It’s time for every elected official in America to make it clear where they stand,” Biden said.
