In my post on Monday, I wrote "789" instead of "788" when referring to the section of Joseph Story's Commentaries on the Constitution of the United States (1833) in which Story refers to the President and Vice President as officers of the United States. In Section 788, Story wrote: "From this clause it appears, that the remedy by impeachment is strictly confined to civil officers of the United States, including the president and vice-president." This mistake has now been corrected.
