In a statement, DSCC spokeswoman Lauren Passalacqua dismissed Tarver’s demand and said Warnock will “continue to be a champion for all Georgians in the Senate.”

Warnock said through an aide that it was “unfortunate that politicians would try to use this for their own personal gain” and that he requests privacy that “most have given his family in this matter.”

Warnock is trying to rally Democrats around his campaign to unseat Republican U.S. Sen. Kelly Loeffler in one of the nation's most-watched political contests, and he's backed by Stacey Abrams and the DSCC, the political arm of Senate Democrats.

Tarver, who entered the race in February, has struggled to gain the same sort of traction. He ended the first quarter of the year with roughly $30,000 on hand, compared with Warnock's $1.2 million campaign bank account.

Asked whether he issued the call to help burnish his campaign, Tarver said the allegations were “too serious to be pushed to the side.”

“It’s not personal,” Tarver said, “but this election means too much to the people of Georgia and the people of the country to cost the Democratic Party a chance at winning this seat.”
