So as cited by the Russia Today the source of this allegation is a Tweet from Ryan James Girdusky -- a person who previously made false allegations against anyone opposing Trump.
Of course,- John Weaver has not been involved with the Lincoln Project since he suffered a heart attack in June. Naturally at that time Ryan and other conspiracy promoters on Twitter claimed it was part of a cover-up and Weaver never had a "cardiac incident".
Once again we are seeing right-wing echo chamber in action.
