Really? You believe a government license would mean reporters would lose their freedom of speech?
I don’t see it that way.
No, but it would mean that they would lose their freedom of the press. The so called "Press" (i.e. corporate media) has no more inherent right to White House access than you or I have when we post on FR, or start a blog.
Do you think the government should be able to license us in order for us to be allowed to post on FR, or publish blogs, or post our videos on YouTube?
Because that's the outcome of what you're advocating.
