In a pair of Truth Social posts Monday evening, Trump took aim at the electric vehicle industry and President Biden’s push for more electric vehicles. With this opposition to electric vehicles, Trump is likely trying to persuade Michigan voters to support him over Biden, who carried the swing state in 2020.

The Biden administration has pushed to boost electric car sales, with the Environmental Protection Agency (EPA) predicting that two-thirds of new car sales could be electric by 2032 under a new proposal released by the administration earlier this year. Last week, the Energy Department announced plans to invest $12 billion into converting auto manufacturing facilities into plants for hybrid and electric vehicles.

Trump also took aim at Shawn Fain, the president of the United Auto Workers, for supporting the Biden administration’s latest investment into electric vehicles.
