"I understand that this is a Republican talking point because I've heard it repeated over and over again ... These numbers have been debunked, as you know... You can't just repeat it and make it true, sir."

I don't know what's gotten into CNN's Soledad O'Brien lately, but, to bastardize apocryphal Lincoln, can we send a whole case of it to the rest of the Beltway Press Corps?

We highlighted a similar moment from O'Brien in June, when she doggedly attempted to get an actual answer from a Senior Romney Adviser on whether the presumptive GOP nominee still supports Arizona's controversial "Papers Please" law. She refused to let it go --- like a real journalist or something.

Again today she went full "Newsroom" on Mitt Romney surrogate John Sununu, the Chair of his National Steering Committing, especially on his attempt to lie about Obama having "gutted Medicare"...
