The billionaire went on to share several posts of conservatives reacting after the ADL listed TPUSA, the far-right student organization Kirk founded in 2012, under its "extremism, hate, and terrorism" label.

Kirk was fatally shot during an event in Utah on September 10, and in the wake of his death, the right has made him into something of a martyr, praising him for his outspoken views on faith and free speech.

But many critics have refused to uplift Kirk's beliefs after his murder, pointing to racist, homophobic, and misogynistic comments he made over the years, as well as his penchant for pushing misinformation and conspiracy theories.

The group also points out that while TPUSA has stated it rejects white supremacist ideology, white nationalists regularly attend their events, where extremists and far-right conspiracy theorists are often invited to speak.

FBI Director Kash Patel says the bureau is cutting ties with two organizations that for decades have tracked domestic extremism and racial and religious bias, a move that follows complaints about the groups from some conservatives and prominent allies of President Donald Trump.

Patel said Friday that the FBI would sever its relationship with the Southern Poverty Law Center, asserting that the organization had been turned into a “partisan smear machine” and criticizing it for its use of a “hate map” that documents alleged anti-government and hate groups inside the United States. A statement earlier in the week from Patel said the FBI would end ties with the Anti-Defamation League, a prominent Jewish advocacy organization that fights antisemitism.

The Anti-Defamation League deleted its “Glossary of Extremism” database on Tuesday after receiving backlash for including the late Charlie Kirk’s Turning Point USA.

In a statement, the ADL announced that it had retired the “extremism” database after its decision to list Turning Point USA – even after founder Kirk’s recent assassination – sparked uproar on social media, including from billionaire Elon Musk and Donald Trump Jr.
