Jon Ossoff has ended speculation about whether he’ll seek a rematch with Rep. Karen Handel in the 6th Congressional District this year, announcing on Twitter that he won’t be a candidate for any office in 2018.

“I’ve decided that this is not the moment for me to run again for Congress,” the Democrat tweeted. “But I’m not going anywhere.”

He said his run for Congress in 2017 “was never about me. It was fueled by the passion of so many Americans to fight back against the obscenity of this presidency and our debased political system.”

In what proved to be the most expensive congressional election in American history, Ossoff fell just short of a majority in an 18-person special election in April and lost to Republican Handel two months later.

Ossoff was trying to become Georgia’s first Jewish congressman in more than 30 years. For now, he’s focusing on the video journalism company he leads while vowing to support other Democratic candidates.

At least two Democrats, Bobby Kaple and Temple Sinai member Kevin Abel, are running against Handel.
