Rudy Giuliani told me that President Trump is fed up with Robert Mueller and wants him to “put up or shut up.”

What he’s saying: “Why don’t you write a report and show us what you have, because they don’t have a goddamn thing. It’s like a guy playing poker. He’s bluffing and he’s only got a pair of twos.”

Trump tweeted twice about Mueller yesterday in terms that were sharper, and with a more personal edge, than the president’s usual rants about the “witch hunt.”

Giuliani said Trump’s view is: “Enough is enough.”
