Michigan Gov. Gretchen Whitmer condemns rhetoric at Trump rally with chants of 'lock her up' - The Washington Post

"Lock 'em all up," he said, as the chants continued amid a sea of red hats. Tori Saylor, deputy digital director for Whitmer, immediately criticized Trump's behavior as dangerous. "I see everything that is said about and to her online," Saylor tweeted. "Every single time the President does this at a rally, the violent rhetoric towards her immediately escalates on social media. It has to stop. It just has to."
