Yeah, they’ve been shit for a long time, going even further back before this.
Here’s an article from 2020 about a leaked memo from the ADL detailing their plans to steelman and justify to the public a full Israeli annexation of West Bank and discourage the US government from stopping Israel.
In 2007, the ADL took heat from the public after then-Director Abraham Foxman opposed Congressional recognition of the Armenian genocide, and subsequently reversed course.
In 1993, Roy Bullock, an independent contractor providing the ADL with intelligence, was caught illegally obtaining documents and spying on various political groups across the spectrum (Greenpeace, anti-Apartheid groups, labor unions, and religious groups), resulting in some of those groups suing the ADL.
And it’s also rumored that from the 50’s through 70’s, they used their position as a civil rights organization to help the CIA spy on other civil rights groups.
