I saw him in an interview recently where he said flat out that he was fired. He also said he knew it would happen eventually and he seemed not to care.
Basically he had enough money to do whatever he wanted the rest of his life and did not need to work.
Nice position to be in, to have enough money to fund a nice retirement. It’s likely he didn’t care if he offended Obama or the suits at NBC.
I don’t watch these comedians very often, but, have gotten the impression that they treated Obama very differently than other presidents. It was open season on joking about Bush, but Obama was not joked about in the same manner.
He seems to be much happier playing with his car collection, and who could blame him?
