(CNN) President Donald Trump is once again trying to pressure a US company to "bring jobs home," expressing displeasure with GM Monday after it closed its Lordstown, Ohio, plant due to shifting customer demand.

"General Motors and the UAW are going to start 'talks' in September/October. Why wait, start them now! I want jobs to stay in the U.S.A. and want Lordstown (Ohio), in one of the best economies in our history, opened or sold to a company who will open it up fast! Car companies are all coming back to the U.S. So is everyone else. We now have the best Economy in the World, the envy of all. Get that big, beautiful plant in Ohio open now. Close a plant in China or Mexico, where you invested so heavily pre-Trump, but not in the U.S.A. Bring jobs home!" Trump said in a series of tweets Monday, renewing a Twitter tirade he launched over the weekend.

UAW is the United Automobile Workers union, which represents GM workers. On Sunday, Trump trained his ire on the local Lordstown UAW president, David Green, calling him a "Democrat" who "ought to get his act together and produce."

The negotiations are being handled by GM and UAW International.

Lordstown is the first of the four US plants GM is closing following its November announcement of a major restructuring. It had 1,435 hourly workers last year at the time the company announced plans to close it. Production at the plant ended this month , and GM has said it will cut 8,000 US salaried and contract jobs.
