petitions are a complete waste, sure they will look at it, blah blah things in place. but I have yet to see someone deported in the USA because people didn't believe with them. disappear forever yes, but not deported
You should say "foreign national". "National" without "foreign" suggests he's a citizen.
There's no legal validity to any such petition, and the protections of the First Amendment extend to foreigners as well. Someone in the US legally may deported under a number of different circumstances, but merely exercising his right to free speech isn't one of them.
We have considerably greater free speech rights in the US than they do in Morgan's home country of the UK. This sort of thing is very embarrassing.
He has the power of CNN behind him? May God have mercy on our souls... What can we do to stop him? It's just pure evil!
Anyway, considering how the blundering American populace actually is stupid enough to believe complete freedom is an actual good thing, I would say yes. I wouldn't be surprised, shocked, or emotionally overturned to use the word flabbergasted, if they allowed it.
Who all for voting Obama off our island? Let me just get that petition going...
"How many signatures make petitions such as these valid? "
25,000 gets the petition reviewed by someone in the Obama Administration. Then the Administration has the option of commenting on the petition. That's it. It is not a legal action, it is not a law making mechanism, it is not a way to enforce, create, or manipulate laws.
