Crap, sorry, just reread Chasfh's statement. I thought it was reported that Bondi was informed Trump was in the file in May. I see Chasfh asked who the source would be Bondi told Trump he was in the files. I apologize for the trouble, I see I was incorrect.
Back to my original statement, Trump surrounds himself with vile humans that will do anything to get ahead. I wouldn't be surprised if Vance, Bondi, Patel...heck Bongino already did a 'either Bondi or I go', any of them could be the source.
Regardless it goes back to what I said previously, it shouldn't be surprising to anyone he's in the files. It still doesn't mean he's guilty of anything, but if he was, I certainly would understand the insistence on trying to change the subject or claiming it's not a real issue.
