1. Maybe Donald Trumps ratings are in the toilet and he's trying to drum up viewers.
2. You still have a bunch of idiots who say he's not an American citizen,this one is funny because when the birthers were passing around that foreign birth certificate, I google translated it and it said nothing of what those morons were passing around and too stupid to check for themselves before the sent out viral emails.
3. Obama's mother is an American, so even if he were born on the moon, he'd be an American, this has gotten so old. Even top Republicans have said that he's an American citizen and it needs to be dropped and move on.
Which leads me to #1. It's all about money for Donald Trump who owes as much as he owns.
