ST. LOUIS (AP) — The president of General Motors announced an investment of $1.5 billion in the company’s Plant in Wentzville that makes trucks and vans.

Mike Parson, Sen. Roy Blunt and other government officials were on hand with GM President Mark Reuss at the Wentzville Assembly and Stamping Plant Friday for the announcement, which also came with the news the company will retain nearly 4,000 jobs at the plat.

GM makes the Chevrolet Colorado and GMC Canyon pickup trucks in Wentzville, and the plant generates $2 billion in GDP annually.

Some lawmakers, both Democrats and Republicans, were critical of the incentive package, saying it failed to guarantee that all GM workers in Wentzville will keep their jobs.

In fact, as part of its new deal with the United Auto Workers, GM pledged to keep 2,000 jobs in Wentzville — less than half of the roughly 4,250 currently employed there.

Missouri Department of Economic Development Director Rob Dixon has said businesses that receive job-retention incentives are required, on average, to keep 88% of their workforce.
