That sounds like more of a weak-arm if they couldn't even muster an investigation, much less consequences. I remember thinking at the time when the Senate called Zuckerberg up to yell at him that if I were Zuck, I would have just said, "thanks for the tax cut, dudes".

And criticizing the system you find yourself in as a result of Citizens United doesn't mean you are not still stuck in that system.

So certainly I welcome politicians of any persuasion who would like to regulate these issues, but as I said, I'm skeptical of the actual intentions.
