You could say companies aren't allowed to spend money to intentionally target or influence elected representatives.

Sure it's hardly defined at all, and maybe I spent 30 seconds on it. But if a jury of my peers unanimously think an exec was trying to influence a representative, then why not levy a huge fine? As far as the legality, is there anything interstate commerce doesn't encompass?
