Veteran political consultant and onetime Trump campaign adviser Roger Stone ripped Robert Mueller and his probe into the president's alleged collusion with Russia.

Tucker Carlson reported that other news outlets have called Stone a "top subject" of Mueller's investigation.

Stone, who began his career as a supporter of 1964 presidential candidate Sen. Barry Goldwater (R-Ariz.) and later worked for President Richard Nixon, said the only possible evidence against him is that he is his role "advocating and working for [Trump's] election."

Stone called the probe and the ongoing coverage of the investigation a "fairy tale" and nicknamed it "Russian collusion delusion," saying Mueller turned up "no evidence" of cooperation with Russia.

He also responded to claims he is closely tied to indicted former Trump adviser Richard Gates.

Stone said he does not remember Gates reportedly working for his former lobbying firm Black, Manafort & Stone, and said he only remembers one dinner with Gates.

Stone appeared incredulous that the dinner would be of concern to Mueller, as he described the event as a meeting to discuss how to properly apportion Trump supporters from New York State for its delegation to the Republican National Convention -- citing the fact New York County, which comprises Manhattan, was the only one of the 62 counties not to award its delegates to Trump in the 2016 primary.

"This whole thing is based on conjecture and speculation," the Connecticut native said, claiming Mueller's team has been "bull-Schiffed" by the top Democrat on the House Intelligence Committee, riffing on Rep. Adam Schiff's (D-Calif.) name. 

Stone added that he is among many people ensared in the Mueller probe who have been forced to spend liberally to defend themselves, also claiming an "Obama-blessed front" advocacy group is suing him in the District of Columbia.
