A criminal complaint was filed in U.S. District Court in Detroit against Vance Pearson, who served as second in command from 2016 to 2018 in the UAW’s so-called “Region 5” that covers 17 western and southwestern states. He subsequently took over the region from Gary Jones, the union’s current president.

The following are highlights of the allegations contained in the complaint:

-- As part of a probe into dealings between the UAW and Fiat Chrysler Automobiles, federal agents discovered a multiyear conspiracy involving “senior UAW officials stealing and unlawfully and willfully abstracting and converting UAW funds to purchase luxury items and accommodations for their own personal benefit” by submitting vouchers that misrepresented payments as official business.

-- In addition to Pearson, who was charged, the complaint named “UAW Official A,” who was not identified but described as a union officer who has held several senior UAW positions. Three unidentified former UAW officials were also named.

-- Federal agents said UAW conferences for Region 5 typically lasted three to five days, but Pearson and others would spend weeks or months living in the same city where they were held, “enjoying an extravagant lifestyle paid for with UAW funds.”

-- More than $600,000 of UAW money paid to the Renaissance Palm Springs Hotel in Palm Springs, California, between 2016 and 2018 was used by the hotel to satisfy debts incurred by senior UAW officials at local businesses, including restaurants, golf resorts and more.

-- Between 2016 and 2018, more than $60,000 of UAW funds were used for meals at the Palm Springs area restaurants LG Prime Steak House and Johnny Costa’s Ristorante.

-- In one instance on New Year’s Eve in 2016, the tab at LG Prime Steak House totaled almost $6,600, including four bottles of Louis Roederer Cristal champagne costing $1,760. The complaint quotes the Louis Roederer website as saying Cristal was “created in 1876 to satisfy the demanding tastes of (Russian) Tsar Alexander II.” The bill also included $1,942 for liquor, $1,440 for wine and what appears to be a $1,100 tip.

-- The UAW paid Indian Canyons Golf Resort more than $80,000 between 2015 and 2018 for food and beverages, green fees, club rentals and the purchase of such items as visors, sunglasses and “fashion shorts.”

-- Agents determined the union paid over $60,000 for cigar and tobacco, humidors, cigar cutters and related expenses between 2014 and 2018 at stores in Palm Springs and Parker, Arizona.

-- Agents found similar spending patterns around Region 5 UAW conferences between 2014 and 2018 at the Loews Coronado Resort in Coronado, California. UAW headquarters paid more than $200,000 to the resort and the union’s Southwest regional council paid more than $195,000. Large sums were spent on chauffeured transportation to private dining events and excursions to the San Diego Zoo’s Safari Park and horseback riding on the beach, as well as more than $70,000 between 2015 and 2018 for green fees at three different golf clubs.

-- Agents also found similar spending patterns around Region 5 events in Lake of the Ozarks, Missouri, where between 2014 and 2018 UAW headquarters paid more than $300,000 to the Lodge of Four Seasons hotel and the union’s Midwest regional council paid more than $190,000. The payments included more than $45,000 for meals and liquor, over $75,000 for golf related expenses, more than $8,000 for spa treatments and over $1,000 spent at a local gun range.

-- Agents described a “culture of alcohol” that existed in the top ranks of the UAW, crediting the term to a cooperating witness who was a senior UAW official. Vendors in Palm Springs told federal agents “there was ‘no limit’ on the amount of alcohol they would purchase for requesting union officials.”

-- Vendor records and witness testimony detailed two parties costing over $50,000 thrown by Norwood Jewell, a former UAW vice president who headed labor relations with Fiat Chrysler. Jewell was sentenced in August to 15 months in prison. His parties featured ultra-premium liquor, a skilled so-called torcedor to roll choice cigars and scantily-clad “kandy girls” to light them.

-- Agents also outlined the search warrants they executed on several homes and work locations of senior UAW officials in late August. Federal officials confirmed at the time that the home of Jones, the UAW president, was among those searched. Thursday’s complaint revealed that agents had seized over $30,000 in cash from the residence of UAW Offical A.
