== Woodrow Wilson == 

 This article fails to mention the pardon granted to George Burdick, a New York newspaper editor, who had refused to testify in federal court regarding the sources used in his article concerning the collection of customs duties. He plead the 5th; President Woodrow Wilson then granted him a full pardon for all of his offenses, which he refused. He continued to plead the 5th, at which he was sentenced by a federal judge for contempt. It was then that the Supreme Court reinforced the necessity of accepting a pardon to be valid; the federal judge had imprisoned Burdick on the grounds that he was claiming falsely his need for protection against self-incrimination. 

 In short, this article overlooks a pretty important pardon. Burdick was released on order of the Supreme Court.
