Eric Holder responds to Rand Paul's filibuster with this letter:
Dear Senator Paul:
It has come to my attention that you have now asked an additional question: "Does the President have the authority to use a weaponized drone to kill an American not engaged in combat on American soil?" The answer to that question is no.
Sincerely,
Eric Holder
Here's an image of that letter:
UPDATE: Apparently, the White House and Justice Department failed to send the letter to the person who asked the question--Rand Paul.
Spox for Sen. Rand Paul on Holder: "We haven't received any letter yet."
