Don't know who the Pinkster is on the left, but the one in the center is Desiree Anita Ali-Fairooz, the same nasty piece of work who protested Condoleezza Rice in the House chambers in 2007 (see below). The little shrimpy one with the stringy blond hair on the right is Medea Benjamin, founder of Code Pink and experienced shake-down artist.
Supposedly, Al Farooz was barred from Capitol Hill after she pulled that stunt on Condi Rice, although I don't know for how long. If the order is still in place, maybe that's why she has dyed her hair.
