Former Rep. Cori Bush, outside the courthouse where the Dred Scott case was argued, promises to reverse her ouster from Congress. Bush, a progressive who started as a Black Lives Matter organizer, lost a primary to Wesley Bell, a more moderate prosecutor. Now, they're in a rematch that highlights Democrats' shifting landscape, including anger at the party establishment and growing support for democratic socialists. Bush blames the American Israel Public Affairs Committee for her previous loss. Bell, dismissing Bush’s attacks, argues he’s a more pragmatic lawmaker. The primary race has national implications, with both candidates accusing each other of corruption.
