Trump had a corrected tweet "McCathyism" changed to "McCarthyism".
When JFK spoke in his thick New England Irish accent, he pronounced "McCarthyism" as "McCathyism".

But, it is missing the R.
So could it also be a reference to JFK Jr. who everybody thought had died.
Well maybe he did die but I expect he is still where the Q movement began, in the boy's investigation of his father's murder.
When he confided his suspicions and findings in Donald Trump, perhaps while they were Freemasons together, Bruce Wayne swore an oath to rid the country of the evil.
Trump has publicly stated that he is Batman
And there is a lot of circumstantial evidence that he was involved in Giuliani's takedown of the Mafia in New York and New Jersey.
