According to Wikipedia ... "It has been alleged that United States President Warren G. Harding was inducted into the Ku Klux Klan during his administration. The evidence is highly disputed."

Article notes that Harding and Truman were accused, but, disputed by too many facts. Whereas, Robert Byrd, Hugo Black and other Supreme Court Justices were KKK.

I don’t know if Harding was actually a member, but I do know that he hosted fully-robed Klan members in the WH and seemed to be quite comfortable with it.
