I can't confirm your quote, but given what I know of Napolitano, it could be something he might say.
One reason I can believe it is because I heard him say, twice, that George Washington was called a "terrorist", and so I figure that Napolitano is generally prone to making historically inaccurate statements.
Here's my link: Lincoln's War
Now, you put up some evidence to back up your leaky memory, otherwise, quit repeating what you can't prove.
