I doubt it, as she was most likely arrested for disorderly conduct inside the House chamber. That crime cannot be justified simply because what was being shouted is (or may be) the truth. If not, then all anyone would have to do to disrupt the proceedings is simply shout something that is true, and they couldn't be arrested.
That's an obvious loophole that cannot be permitted as a defense. The crime here is simply disrupting the peace; it doesn't matter if the disruptor is "right" or not; it can't matter or else such rules/laws have no waymof being enforced.
