Swearing to uphold a draft of the Constitution that does not include the Bill of Rights "is probably not the symbolism the White House wanted," notes Olivier Knox at Yahoo! News.
Blogger "Emptywheel" writes that Brennan "was swearing on [a draft] that did not include the First, Fourth, Fifth, or Sixth Amendments -- or any of the other Amendments now included in our Constitution. The Bill of Rights did not become part of our Constitution until 1791, 4 years after the Constitution that Brennan took his oath on."
