Got any sources about the elder Ickes being a mole (of the Soviets, I take it) in the FDR administration? I knew he was a red-hot leftist, but the big shot in that administration that has been most identified as a mole is Harry the Hop Hopkins (who actually lived in the White House all through WWII).
Clinton and Ickes went to lots of trouble to make it look like Ickes was fired and banished from the White House, but he then magically turned up back in NY and running Hillary's Senate run. Few papers reported this.
My theory has always been that Ickes was the true evil power behind the Clintons. Check, "Who is Harold Ickes?" in the Wall Street Jounal.
I don't know how many history books you've read, but I've read of it many.
