FBI agents carry materials out of the home of United Auto Workers President Gary Jones on Wednesday, Aug. 28, 2019.

DETROIT – Federal agents raided the home of United Auto Workers President Gary Jones on Wednesday as the Justice Department expands its probe of corruption in the union's top ranks while Detroit automakers renegotiate labor contracts for 158,000 employees.

Kevin Telepo, a neighbor, said he noticed FBI and IRS agents searching the property at about 8:30 a.m. The agents removed "a bunch of boxes" from the house and "were going through a bunch of cash in the garage," he said in an interview.

The federal agents were still searching Jones' home in suburban Detroit and removing items in the early afternoon.

Jones' home was one of several targets hit by federal agents Wednesday, according to FBI spokeswoman Mara Schneider. Other locations in the multistate raid included the California home of former UAW President Dennis Williams as well as the union's training center, golf resort and a conference center called Black Lake.

Additional locations, Schneider confirmed, included a local UAW office in Missouri, where Jones previously served as regional director, and the Wisconsin home of Williams' former administrative assistant, Amy Loasching.

The raids, which were first reported by The Detroit News, occurred at six locations in four states. They mark a major shift in the investigation from many former or retired union officials being targeted to active leaders.

The Department of Labor's Office of Inspector General also was involved in the raids, Schneider confirmed.
