President Trump fired Secretary of State Rex Tillerson on Tuesday, over Twitter and reportedly without telling Tillerson first, Jimmy Kimmel noted on Tuesday's Kimmel Live. "Trump told reporters he made this decision 'by myself.' Right, like a 5-year-old — 'I did it all by myself.' Of course you did it by yourself, there's no one left at the White House anymore. It's just you and your Slovenian captive." The audience wasn't sure about that last joke.
