David Letterman’s 33-year run on late-night television was marked by his acerbic sense of humor.
Upon retiring in 2015, he’s undergone a metamorphosis into someone almost unrecognizable from the more comedic guy people watched on the “Late Show with David Letterman”.
He’s grown a full beard, which coupled with his balding head, makes him look like a guy wanting to moonlight as a department store Santa Claus.
But beneath that kindly-looking exterior lurks a clearly bitter and troubled man, as evidenced by recent nasty remarks about President Donald Trump.
It’s spelled out on the next page. See how the funny guy seems to have lost his sense of humor.

Must be a really slow news day that you have to keep running this story about this has-been.
Letterman is worthless, Always has been

Letterman did an interview years ago where he said he really knew nothing about politics and could only joke
How is it that the leftist Hollywood elite can call Trump ignorant? How many of them have made a Billion Dollars?
