The claims suggest UAW president Shawn Fain made demands to benefit his domestic partner and her sister|@UAW|X

A federal watchdog is investigating new allegations against United Auto Workers President Shawn Fain, claiming he made demands to benefit his domestic partner and her sister— sparking a dispute over access to union documents.

Neil Barofsky is examining if Fain’s decision to remove UAW Vice President Rich Boyer was retaliatory. The investigation follows a 2020 settlement addressing union corruption.

Fain, elected in 2023, led the UAW to big contract wins in Detroit after a six-week strike at GM, Ford and Stellantis. However, the union, under his leadership, faces ongoing scrutiny amid efforts to rebuild.
