There's at least one constant in a government shutdown: The 532 members of Congress continue to be paid - at a cost of $10,583.85 per hour to taxpayers.
Lawmakers get their pay even as hundreds of congressional staffers are sent home, packs of tourists are turned away at the Capitol, and constituent services in many offices grind to a halt.
House members and senators can't withhold their own pay even if they want to. Under the Constitution's 27th Amendment, lawmakers can only change the pay of those in a future Congress, not the one in which they serve.
Lawmakers aren't oblivious to how it looks. Republican Sen. Ted Cruz and others are pledging to donate their salaries to charity during the shutdown.
