For those with a little trouble following along, Ms. Kerry is addressing the Pennsylvania delegation to the Democrat convention and decries "un-Pennsylvanian and un-American traits" that have been creeping into politics towards the end of her speech.
A reporter from the Pittsburgh Tribune then asks her what she meant by "un-American". She denies she said it, not once but twice and asks why the reporter is putting words in her mouth. Then, after leaving, she storms back at the reporter and tells him to "shove it".
Her media handler then excuses her outburst because of who the reporter works for.
Don't expect to see this on CNN, CBS, NBC, ABC, PBS or the rest of the unfair and unbalanced media. But the proof is there, captured by a Pittsburgh TV station.
