The video shared by Donald Trump features horror movie music and footage of migrants purportedly entering the U.S. from countries including Cameroon, Afghanistan and China. Shots of men with tattoos and videos of violent crime are set against close-ups of people waving and wrapping themselves in American flags.

“They’re coming by the thousands,” Trump says in the video, posted on his social media site. “We will secure our borders. And we will restore sovereignty.”
