Michelle Obama, who campaigned hard for Hillary Clinton, took a parting swipe at Trump when the TV titan asked the question: “Your husband's administration, everything, the election was all about hope. Do you think this administration achieved that?"

“Yes, I do," she responded. "Because we feel the difference now. See, now we're feeling what not having hope feels like, you know? Hope is necessary. It's a necessary concept. And Barack didn't just talk about hope because he thought it was just a nice slogan to get votes.”

The Oprah Winfrey Special, First Lady Michelle Obama Says Farewell to the White House, airs Monday night on CBS.
