No they didn't

I guess the truth is that they indeed didn't. That is, the House of Represetatives didn't reject their pay raise. Their cost of living increase is automatic unless they vote to reject it, which was in fact proposed by two congressmen. We can ask teens to "just say no," but don't expect Congress to do so. They rejected the proposal to reject the pay raise. The final vote: 244-181. So, it looks like they'll get their automatic cost of living increase.

But I'm proud of 'em. There was bi-partisan support in favor of keeping their raise, led by Majority Leader Steny Hoyer and Minority Whip Roy Blunt. No immigration reform; no health care reform; no social security reform, but the House could come together in favor of themselves. Bravo!
