The federally appointed monitor tasked with overseeing the United Auto Workers, Neil Barofsky, is ratcheting up his conflict with UAW President Shawn Fain, announcing another investigation into the union leader who rose to national prominence amid the successful “Stand Up Strike” against the Big Three automakers.

Yet newly unveiled documents suggest Barofsky’s pursuit of Fain has less to do with concerns over union self-dealing and more to do with the politics of Israel-Palestine.

Barofsky was appointed in 2021 as the result of the Department of Justice-led consent decree put in place in lieu of prosecution of the union itself for rampant corruption, following prison sentences for two consecutive UAW presidents.
