In a move to trim production and labor costs under bankruptcy protection, General Motors is closing plants, including one in the Mansfield area and part of another in Parma.

A service and parts warehouse in Columbus also will be closed. U.S. Senator Sherrod Brown (D-OH) issued a statement regarding this morning's bankruptcy filing.

"This is a challenging time for Ohio auto communities and for manufacturers across the state. My thoughts are with GM workers, their families, and the thousands of other Ohio workers whose livelihoods are tied to those of GM," Sen. Brown said.

He also said he felt Ohio auto communities deserved to know why certain plants were picked for closure while others remained open.

"Auto workers in Mansfield, Groveport, and Parma are among the most productive workers in the nation. We need a coordinated federal response that invests in these workers and their communities," he said.

Sen. Brown went on to say he would continue to work with President Barack Obama and the administration to "ensure the needs of auto workers and communities are met with a timely and targeted federal response."

The Parma facility will lose 100 jobs and the stamping plant in the Mansfield area will close next year. GM's largest northeast Ohio plant will remain open.

The Lordstown facility employs 2,250 workers. GM says the plant is among the highest volume single line vehicle assembly facilities in the world with total volume at over 14-million vehicles since production started in 1966.
