Changes in Advisors and White House Staff from The Takeaway: Early Edition

My friends that work, do business in D.C. are too cool for books like this. But I dig the commercial fiction, Dan Brown flair and how current it is (with notes citing meetings from just a couple of months ago); I'm a little naive, so details about little security features about various Federal buildings (such as "secured rooms" for discussing classified information) are interesting to me.
