Yes, this was a McCain aided attempt at a hit job.
Trump needs to sit down with McConnell, and make him understand that this crap has to stop, now, and that McCain and his GF Linda need to get in line. More crap out of them, and they will be stripped of all their committee seniority and put on a couple of minor committees that don’t get any budget slice.
Acc to BBC, British Spy who compiled the Trump document was then working for "a super PAC supporting Jeb Bush"
