(CNN) A former General Motors worker of 40 years said Wednesday President Donald Trump's recent statements about the company's decision to close plants and lay off workers "offensive."

"We are the magic wand. We are the people that kept GM here all that time," Carmela Denno told CNN's Poppy Harlow on "Newsroom."
