Turning Point USA ripped Vivian Kubrick, the daughter of legendary director Stanley Kubrick, on Friday for posting an unhinged social media rant against Erika Kirk.

“Who even is this woman?” a TPUSA rep clapped back. “I’ve heard of her father, but I had to look her up and what a joy. She’s the seemingly estranged daughter of Stanley Kubrick, who became a Scientologist and a rabid fan of the Candace cult.”

“It’s clear she’s been radicalized by the same mind virus as those who attack Erika Kirk and Charlie’s legacy. We wish her well and are praying she gets the help she needs,” the rep added.

Vivian Kubrick posted on X that a pre-recorded video address from the widow of conservative icon Charlie Kirk — in which she reflected on her own husband’s death and the Christian faith — was “ghastly” and “inauthentic.”

She also called on President Trump to “kill” TPUSA — which improved youth Republican voter turnout by as much as 10 percentage points between 2020 and 2024 — “if we’re to win the midterms.”

“[L]et some honest to God, authentic, super smart young patriots rally the American youth,” Kubrick said.

Vivian Kubrick has credited Scientology with saving her life in the 1990s, according to social media posts.

Her father, regarded as one of the most influential filmmakers of the 20th century, died in 1999 at age 70.

Erika Kirk, in the video, had addressed supporters about her husband’s legacy at Prestonwood Baptist Church in Plano, Texas, during Turning Point USA’s “Make Heaven Crowded” tour.

Earlier Wednesday, she had also called out an “epidemic of dehumanization” sweeping the US, in the wake of a third assassination attempt against President Trump at the White House Correspondents’ Association Dinner.

She took over as CEO of TPUSA after alleged gunman Tyler Robinson assassinated her husband on Sept. 10 at Utah Valley University during a speaking engagement.

“Having lived through quite literal hell these past seven months, if you strip someone of their humanity long enough, you will arrive at the chilling conclusion that they don’t deserve to exist at all,” she posted in a video message on X.

Kirk attended the dinner at the Washington Hilton on April 25 — and was quickly rushed out after an armed gunman tried to breach the ballroom where Trump and several administration officials were in attendance.

Accused shooter Cole Tomas Allen, 31, was later charged with attempted assassination, transporting a firearm across state lines to commit a felony and discharge of a weapon during a crime of violence.
