GM will effectively halt production next year at five plants in North America — in Ohio, Michigan, Maryland and Ontario — as well as two plants outside of North America.
The company also plans to cut 15 percent of its salaried workers. The cuts will eliminate more than 14,000 jobs in all, roughly 8,100 white-collar positions and more than 6,000 factory jobs, according to GM.
Overall, GM estimates the reorganization will save about $6 billion a year by the end of 2020.
"We are the hottest economy in the world right now," Kudlow said last month.
Trump also praised General Motors last year, saying the automaker was "starting the big jobs push back into the U.S." Trump had pledged to revive manufacturing in an Ohio region where GM now plans to slash production and layoff workers.
"Jobs have left Ohio," Trump said in 2017, but "they're all coming back."
GM plans to cut as many as 1,600 factory jobs at a Lordstown, Ohio, plant — 20 miles away from where Trump spoke when he promised to return jobs to the area.
