Petition the whitehouse to investigate Pizzagate

Of course they are, and of course signing a petition won't actually bring about an investigation; they never do. You sign the petition to let the government know that you're fucking fed up with the bullshit.

The government always has and always will play by its own rules. All we CAN do is formally bitch about it. I'd much rather do that to their faces than do it anonymously in the comforts of obscure web forums.
