Re: Round 1?
There's no law that says any private company has to treat people equally based on their political views. In fact, quite the opposite -- the nearest equivalent would be the Fairness Doctrine and that was eliminated decades ago. It's also very common for corporations to attempt to influence elections -- they just can't coordinate with campaigns to do it. The NRA, for example, has no problem with endorsing candidates and even has an enemies list of sorts.
You can argue that it's unethical to pick and choose based on politics, but it's not illegal. If it were, outlets like Fox News and The Blaze would not exist, so I think Nunes might want to be careful about opening that can of worms.
