Jon Stewart takes over The Late Show to take on President Trump's immigrant family separation controversy

“Hello, Donald. It’s me, the guy you made sure everyone knew was Jewish on Twitter,” Stewart, a Late Show executive producer, said in briefly taking over Stephen Colbert's desk. “I know you’re upset about all the criticism you’ve been taking in the ‘fake news’ and the ‘fake late-night shows.’ It’s just that we’re still having a little trouble adjusting to your presidency as it goes into its 500th year.” The former Daily Show host said of Trump's immigrant family separation controversy, “Boy, you f*cked that up.” Stewart added: “Clearly, we’re not going to be able to negotiate or shame you into decency, but there is one place where I draw the line: I won’t allow you and your sycophants to turn your cruelty into virtue."
