Napolitano, a former superior court judge in New Jersey, currently works as a legal analyst for Fox News. In a pair of tweets Saturday evening following his campaign rally in Green Bay, the president accused the commentator of becoming “very hostile” after Trump supposedly turned him down for the nation’s highest court.

“Thank you to brilliant and highly respected attorney Alan Dershowitz for destroying the very dumb legal argument of “Judge” Andrew Napolitano,” Trump wrote.

“Ever since Andrew came to my office to ask that I appoint him to the U.S. Supreme Court, and I said NO, he has been very hostile! Also asked for pardon for his friend. A good ‘pal’ of low ratings Shepard Smith,” the president added, referring to the afternoon host of Fox’s newscast that has often been critical of the White House.

Update: Here’s Napolitano’s reply.
