The FBI and IRS raided the home of United Auto Workers (UAW) President Gary Jones on Wednesday morning, as apart of a corruption probe on the autoworkers union.

Federal authorities have also raided UAW locations across the country, including their conference center in northern Michigan looking for evidence to bolster their ongoing corruption probe against the influential union.

Jones’ home in Canton, MI, a suburb of Detroit, was raided by up to 12 federal agents who scoured his domicile collecting evidence earlier today. Federal authorities conducted what they call a “knock and announce” raid and refused to say whether anyone was home when it was executed.
