Trump shared his opinion about General Motors idle car plant in Ohio over a series of four tweets yesterday, demanding that GM reopen the plant to create jobs for Americans. Trump’s campaign was founded on the idea of keeping jobs in America and discouraged outsourcing labor. General Motors and the United Auto Workers (UAW) union is scheduled to discuss next steps in September. Trump made his impatience known over his tweet, saying that the two parties should discuss the issue now, and included the current unemployment rate in his message.
