Challenger Corey O’Connor ousted Pittsburgh Mayor Ed Gainey in Tuesday’s Democratic primary election, beating an incumbent in a race that hinged on how Gainey was handling city finances, affordable housing and public safety.

Pittsburgh Mayor Ed Gainey, who had allied himself with progressives, has lost a Democratic primary challenge, The Associated Press reported. The AP called the race for Alleghany County Controller Corey O'Connor at 10:05 p.

Ed Gainey, who was elected to be Pittsburgh’s first Black mayor nearly four years ago, will face Corey O’Connor, the Allegheny County Controller and well-funded son of a beloved former mayor. The primary will probably decide the general election as well, since Pittsburgh has not elected a Republican mayor in nearly a century.
