Public servant with integrity versus public abuser with none.
Via The Blaze:
In March 2004 President George W. Bush needed the attorney general to certify the legality of the National Security Agency electronic surveillance program. Attorney General John Ashcroft was hospitalized at the time and his deputy, James Comey was acting attorney general.
The Department of Justice disagreed with the White House position on the NSA warrantless wiretapping program and demanded changes in it in order to certify it.
Comey refused to sign the document and wrote a letter of resignation to be delivered to the president if the program were to continue without the changes.
