"Very disappointed by General Motors," said the president on Twitter. His warning came a day later GM announced a 15% reduction in the labor force and closure of five factories in the US, two of them in places like Michigan and Ohio as Trump won tightly in the 2016 election.
"The United States has saved General Motors and here are the ACKNOWLEDGMENTS we have! We are considering eliminating all subsidies, even for electric cars, "he added.
GM said that its decision was based on a weak sale of small cars mounted in these two factories, indicating that it wants to control its efforts against autonomous cars and other new technologies.
American vehicle manufacturers also suffer from charges on aluminum and steel, but GM said it did not affect their decision.
Currently, the United States offers subsidies of between 2,500 and 7,500 dollars for each electric vehicle depending on the model. GM produces all-electric Chevrolet Bolt, but that kind of car gives a lot of money to the company's revenue.
