WSJ has the story, in all it's ironic glory:
Protesters who attended Saturday’s Tea Party rally in Washington found a new reason to be upset: Apparently they are unhappy with the level of service provided by the subway system.
Rep. Kevin Brady called for a government investigation into whether the government-run subway system adequately prepared for this weekend’s rally to protest government spending and government services.
The Texas Republican on Wednesday released a letter he sent to Washington’s Metro system complaining that the taxpayer-funded subway system was unable to properly transport protesters to the rally to protest government spending and expansion.
Yeah, and after he gets to the bottom of that "mystery", perhaps he can team up with O.J. to find the real killer!
