There are 435 representatives (not to mention 100 senators) and McKinney expects the security guards to recognize them all? She needs to follow procedures; i.e., wear her pin, if she expects to be "recognized" and not asked for identification.
I'm from Georgia, and I didn't recognize her immediately with the new hairdo - and I don't think it's nearly as flattering as the way she used to wear it.
You're being kind - I think it looks like it was done with a chainsaw...
