President Donald Trump ridiculed the special counsel investigation by Robert Mueller of whether or not his presidential campaign colluded with Russia while winning the election.

The New York Times on Monday revealed a list of questions that Mueller wanted to ask Trump about possible ties to Russia and whether he was trying to obstruct the investigation.

“So disgraceful that the questions concerning the Russian Witch Hunt were ‘leaked’ to the media,” Trump wrote on Twitter on Tuesday.

The president mocked the investigation, pointing out that the accused “crime” of collusion was a “phony crime.”

“No questions on Collusion. Oh, I see…you have a made up, phony crime, Collusion, that never existed, and an investigation begun with illegally leaked classified information,” he wrote. “Nice!”

The list includes questions about his son-in-law Jared Kushner setting up a back channel to Russia, communications with Roger Stone Jr, discussions of a possible pardon for Michael Flynn, conversations with Attorney General Jeff Sessions, whether he had knowledge of his former campaign manager Paul Manafort’s communications with Russians, and details of his 2013 trip to Russia for the Miss Universe pageant.
