BOR was a joke. He apologized at one point in the interview.
And because he “landed” the Obama interview, he has gone soft on him. Yesterday, he didn’t think the “lipstick” comment was done purposefully. Pure idiot.
Today, O'Reilly played the whole Letterman rif about the lipstick and laughed that Obama has become a stand up comedian. I guess O'Reilly has forgiven Letterman for his treatment of him.
