There's a great photo from the National Review.
I know it's a sad testimony to my love of political wrangling, but this is tremendous fun. That flag was flown by Republican members.
There is a story about racial name-calling of Congressional members by a "mob" - IF TRUE - and I doubt it, there is NO video to match the accusation - it would be a shame on those individuals.
HOWEVER, my suspicion is that it's a total hoax, just like previous accusations, which were proven to be made up. The original accusation gets air play, the retraction doesn't.
