A Twitter post from the account of Jason Kessler, the far-right activist who organized the Charlottesville, Va., “Unite the Right” rally, insulted the protester who was killed at the event, saying late Friday night that her death was “payback time.”

“Heather Heyer was a fat, disgusting Communist,” the post said. “Communists have killed 94 million. Looks like it was payback time.”

The post linked to a story on neo-Nazi website the Daily Stormer that also insulted Heyer in crude terms and appeared to take glee in her death.

Kessler did not respond to messages seeking comment.

Police say Heyer was killed when a rally attendee, James A. Fields, drove his sports car into a crowd of counterprotesters at the event Aug. 12, which drew white nationalists, neo-Nazis and other far-right figures from around the nation.

Fields has been charged with her murder. Kessler had blamed city officials for not providing sufficient security for the rally, which was organized to protest the removal of a statue of Confederate Gen. Robert E. Lee from a Charlottesville park.

Kessler’s Twitter post sparked denunciations from other far-right rally attendees, who quickly distanced themselves from him, accelerating a spiral of recriminations that have been brewing among far-right leaders over who was to blame for the chaos behind last weekend’s violent “Unite the Right” rally.

On Saturday morning, the post had been deleted from Kessler’s account, which initially claimed he’d been hacked, but then backtracked and said he’d been on a mixture of drugs.

“I repudiate the heinous tweet that was sent from my account last night. I’ve been under a crushing amount of stress & death threats,” the post said. “I’m taking ambien, xanax and I had been drinking last night. I sometimes wake up having done strange things I can’t remember.”

Kessler’s posts then were switched to “private” mode before his account was deleted entirely.

“I will no longer associate w/ Jason Kessler; no one should,” Richard Spencer, a white nationalist who was scheduled to speak at Kessler’s event, said on Twitter. “Heyer’s death was deeply saddening. ‘Payback’ is a morally reprehensible idea.”

Another far-right figure who attended the event, Tim Gionet, who goes by the name Baked Alaska, also criticized the remarks.

“This is terribly wrong and vile,” Gionet posted. “We should not rejoice at the people who died in Charlottesville just because we disagree with them.”
