The Federal Bureau of Investigation (FBI) in the United States has announced that the bureau will end its partnership with the Southern Poverty Law Center (SPLC), as it seeks to distance itself from organisations it accuses of political bias.

On Friday, FBI Director Kash Patel posted on social media that “all ties with the SPLC have officially been terminated”.

“The Southern Poverty Law Center long ago abandoned civil rights work and turned into a partisan smear machine,” Patel wrote.

He reserved criticism for the centre’s interactive “hate map”, which identifies groups associated with hate and antigovernment activity and maps their bases of operation.

“Their so-called ‘hate map’ has been used to defame mainstream Americans and even inspired violence. That disgraceful record makes them unfit for any FBI partnership,” Patel said.

Patel’s announcement marks the second time this week the FBI has severed ties with a group that seeks to track threats to civil rights.

On Thursday, the FBI also cut ties with the Anti-Defamation League (ADL), accusing the Jewish advocacy group and anti-Semitism watchdog of spying on conservatives.

The announcements amount to a dramatic rethinking of longstanding FBI partnerships with prominent civil rights groups, at a time when Patel is moving rapidly to reshape the nation’s premier federal law enforcement agency.

Over the years, both organisations have provided research on hate crime and domestic extremism; law enforcement training; and other services. But they have also been criticised by some conservatives for what they claim is an unfair maligning of their viewpoints.

That criticism escalated after the assassination of conservative activist Charlie Kirk. Outrage after Kirk’s shooting brought renewed attention to the SPLC’s characterisation of the group Kirk founded, Turning Point USA.

For instance, the SPLC included a section on Turning Point in a report titled “The Year in Hate and Extremism 2024” that described the group as a “case study in the hard right”.

Prominent figures including Elon Musk lambasted the SPLC this week about its descriptions of Kirk and the organisation.

“Incitement to violence by evil propaganda organisations like SPLC is unacceptable,” Musk wrote. He added, “This is getting innocent people killed,” without elaborating further.

A spokesperson for the SPLC, a legal and advocacy group founded in 1971, did not directly address Patel’s comments in a statement Friday.

But the spokesperson said the organisation has shared data with the public for decades and remains “committed to exposing hate and extremism as we work to equip communities with knowledge and defend the rights and safety of marginalised people”.

Criticism from the far-right of the SPLC stretches back well before Patel’s announcement.

Republican lawmakers have long accused the SPLC of unfairly targeting conservatives. In October 2023, Senators James Lankford and Chuck Grassley urged the FBI to cut ties with the group, calling it biased and unreliable for labelling faith-based and conservative organisations as “hate groups”.

They argued that the SPLC was not a neutral civil-rights watchdog, but a partisan actor whose data must be banned from official use.
