Congressman Johnson replaced Cythia McKinney

Congressional Oversight in Action
[Mark Steyn]
Watching the Commander of the Pacific Fleet's deadpan face as Congressman Hank Johnson (D., Ga.) asks him about the danger of the island of Guam tipping over and capsizing is a glimpse of how the viziers to the loopier Ottoman sultans must have felt.
Presumably, when you're the head guy of a major fleet for a big-time navy, you've got plenty of other ways of filling your time other than reassuring congressmen on whether miscellaneous land masses are likely to tip over and sink. But it's business as usual in Congress. The Toyota execs hauled up to account for an entirely mythical epidemic of runaway Priuses surely had similar feelings — as will the Verizon/Caterpillar/John Deere CEOs summoned by Henry Waxman to explain why they had the lèse-majesté to factor the costs of Obamacare into their federally required earnings statements.
I understand Representative Johnson is ill. The fact that this plea is entered in mitigation rather than as grounds for retirement says a lot about what's wrong with Congress.
