U.S. Secret Service took an employee of a Chicago restaurant into custody Tuesday evening after she spit on President Donald Trump’s son Eric Trump, the president’s son told Breitbart News.

“It was purely a disgusting act by somebody who clearly has emotional problems,” Eric Trump told Breitbart News when reached by phone late Tuesday evening. “For a party that preaches tolerance, this once again demonstrates they have very little civility. When somebody is sick enough to resort to spitting on someone, it just emphasizes a sickness and desperation and the fact that we’re winning.”
