(Breitbart) Noted Ronald Reagan historian Craig Shirley has doubled down on his plagiarism charge against liberal author Rick Perlstein. Shirley accused Perlstein of improperly citing or entirely failing to cite Shirley’s 2005 book, Reagan’s Revolution, in his new book, The Invisible Bridge: The Fall of Nixon and the Rise of Reagan.
Last month, Brietbart News reported that Perlstein’s book, published by Simon and Schuster, used online notes and citations instead of traditional ones, and Shirley pointed out over 50 instances in which he believes his books were used without accreditation.

Now, Martin Wooster, an author, researcher, and editor who was contacted by Shirley’s attorney to conduct an independent investigation, has released a report noting the similarity between Shirley and Perlstein’s works.
