Gary Jones, the president of the United Automobile Workers union, which is under investigation over allegations of financial wrongdoing, is taking a leave of absence, the union said in a statement on Saturday.
The union said Mr. Jones sought the leave of absence after a vote by its executive board. The statement did not elaborate on the board’s vote and Mr. Jones could not be reached on Saturday for comment. Mr. Jones has not been charged with wrongdoing in the investigation.
In August, agents from the Federal Bureau of Investigation raided his home in Canton, Mich., and executed search warrants at a U.A.W. resort in Michigan and other locations, the agency said at the time.
In particular, investigators have been looking into the resort, Black Lake, a rustic lakeside conference center with golf courses, tennis courts and log-cabin style architecture in Onaway, Mich., about 250 miles north of Detroit.
The union is building a cabin on the property to be used by Dennis Williams, who was its president from 2014 to 2018. Union workers have been critical of the move, but a U.A.W. spokesman told The Detroit Free Press in January that the cottage was owned by the U.A.W., not Mr. Williams.
The federal investigation has uncovered the improper use of millions of dollars of funds and bribery of union officials by auto executives, leading to the indictment of several people. In some cases, money was spent on personal travel, Rolex watches and other high-priced items.
In the statement, Mr. Jones said the union was fighting for its members.
“I do not want anything to distract from the mission,” he said. “I want to do what’s best for the members of this great union.”
Mr. Jones will begin his leave on Sunday. The union’s vice president, Rory Gamble, will serve as interim president.
The news of his leave of absence comes after the union recently reached agreements with General Motors and the Ford Motor Company following a strike that lasted more than a month. The U.A.W. is one of the largest unions in the United States, with more than 400,000 active members.
Federal officials have been investigating the union and its managers for some time. In July 2017, Alphons Iacobelli, the former head of labor relations at Fiat Chrysler Automobiles, was indicted on conspiracy and other charges by a federal grand jury.
According to the indictment, Mr. Iacobelli used money from a union account to pay for a $350,000 Ferrari sports car, two gold Montblanc pens and a new kitchen and swimming pool at his personal residence. Federal investigators said he also allowed $1.2 million that was meant to pay for a training center to be diverted to a U.A.W. official and his wife.
He pleaded guilty in August 2018 to violating federal labor law and was sentenced to five and a half years in prison, The Free Press reported. He said at the time that he would cooperate with federal investigators.
More recently, in April, Norwood Jewell, a former U.A.W. vice president, pleaded guilty to breaking federal laws, The Free Press reported. He was accused of spending lavishly on $7,000 steakhouse dinners, cigar and wine parties valued at $30,000 and stays at golf resorts.
