Rep. Bradley Byrne, R-Ala., is set to announce his candidacy on Wednesday for what arguably has been the nation’s most-watched Senate seat for the past two years.

The seat is currently held by Democrat Doug Jones, who won a circus of a special election over controversial former Alabama Supreme Court Chief Justice Roy Moore, to fill the remainder of the term vacated by Jeff Sessions when Sessions became U.S. attorney general. Moore, the famous “Ten Commandments judge” twice evicted from his high court spot for ethics charges related to his defiance of federal court orders, saw his campaign hobbled by multiple allegations that he “dated” or tried to date teenagers while he was in his 30s or older.
