The source that you provided, MSN, likely took this finding from another news source or news outlet. First I believe it is important to find the original source and link to the original findings. The first of the credible sources that I found was Reuters (Reuters), reporting that the FBI under Patel has formally ended its partnership with the ADL, quoting him directly: “We won’t partner with political fronts masquerading as watchdogs.” In addition, I found Newsweek (Newsweek) saying, "Patel said that past collaborations between the FBI and ADL under Comey blurred the lines between law enforcement and advocacy organizations. He alleged on X that Comey “wrote ‘love letters’ to the ADL and embedded FBI agents with them."
Although each source may have minor biases, I believe that overall each source is pointing to the same answer that, yes Petel did cut off the ADL, but it is because of its relationship withe previous FBI director.
In his public declaration that he would not collaborate with the ADL, Kash Patel brought up James Comey's previous association with the group. Although it oversimplifies the decision's larger logic, the claim accurately captures Patel's remarks.
