Attacks Jon Stewart's heritage in Twitter feud

Trump engaged in a Twitter feud with Jon Stewart, calling him "Little Jon Stewart" and highlighting Stewart's birth name (Jonathan Leibowitz) in an apparent attempt to call attention to his Jewish heritage. The attack came after Stewart mocked Trump, referring to him as "Fuckface Von Clownstick."

"I promise you that I'm much smarter than Jonathan Leibowitz - I mean Jon Stewart @TheDailyShow. Who, by the way, is totally overrated." — Tweet sent on April 24, 2013 (part of ongoing March-May feud)
