WASHINGTON, Oct 10 (Reuters) - United Auto Workers

President Shawn Fain on Thursday said hundreds of thousands of

U.S. jobs were at stake if former President Donald Trump won the

Nov. 5 presidential election and made good his promise to revoke

the Inflation Reduction Act and its investments in electric

vehicles.

Democrats have seized on comments from Trump's running mate,

U.S. Senator JD Vance of Ohio, in which he declined to commit to

maintaining the $500 million investment to help GM

convert an old Cadillac plant into an electric vehicle facility,

arguing that removing the funds risk some 650 jobs in Lansing,

Michigan.

"It's a lot bigger than just the Lansing Grand River

investment. It's factories all over the United States, and it's

supply chain factories all over the United States that are being

put in place now. So you're talking hundreds of thousands of

jobs that Donald Trump is just writing off," Fain told reporters

ahead of a Trump visit to Detroit later on Thursday.
