The first general election ad released by her campaign splices clips of Trump threatening protesters and mocking a disabled reporter with scenes of Clinton visiting factories, greeting diverse groups of voters and stepping off a plane as secretary of state.
She ends the one-minute spot saying: "What kind of America do we want to be? Dangerously divided or strong and united? I believe we are always stronger together."
Trump responded Sunday on Twitter: "Clinton made a false ad about me where I was imitating a reporter GROVELING after he changed his story. I would NEVER mock disabled. Shame!"
