This is exactly how press conferences should work. When someone holds a press conference, their opposition should crash the stage, take to the microphones, and trash the person or organization holding the press conference!
And that's exactly what happened when Andrew Breitbart, a notorious conservative blogger, did when he attended a press conference being hosted by Representative Anthony Weiner. You can watch Breitbart's portion of the press conference over at CBS' YouTube account here.
Brietbart's actions today reminds me of a certain rapper's stunt a few years back on an MTV awards show.
