I came across this letter from David A. Keene (American political consultant, former Presidential advisor, and newspaper editor. Keene worked for the political campaigns of Ronald Reagan, George H.W. Bush, Robert Dole, and Mitt Romney.)
The memo concerns George Clark (Republican leader from Brooklyn and ally of Ronald Reagan).
The memo is a photocopy, but the note is allegedly handwritten by Reagan. It is being sold by a representative of the Raab Collection who I've heard of but have no idea on they're authenticity. Any opinions would be very appreciated!
