A White House correspondent spills details about the 79-year-old president’s odd lifestyle on the Daily Beast Podcast.

President Donald Trump’s fast-paced days and sleepless nights show he knows the clock is ticking, according to a veteran White House correspondent. In a new episode of The Daily Beast Podcast, ABC News’ Jonathan Karl joins a chorus of officials and reporters flagging the 79-year-old man’s unconventional lifestyle and why “the guy really seems to have a lot of energy.” “He’s not sleeping. I don’t know how he does it,” Karl told host Joanna Coles. “He gets calls late at night. During the campaign, if I wanted to call him, I figured the best time to reach him was either late at night—much later than most other people would call—and very early in the morning. So sometimes I’d talk to him before seven, and he was already up. He was already watching TV.”
