Amazing how they still continue to do so. In his bestseller One Summer: America, 1927 (New York: Random House, 2013), Bill Bryson charged that Hoover was a totally humorless and dishonest money-grubber and that his considerable charitable activities were motivated by greed and involved massive corruption. Bryson's sole source of evidence for these charges was a campaign book promoting Franklin D. Roosevelt during the 1932 presidential campaign that the author repudiated after FDR won the election.
Bryson is an Iowa fraud.
