So, is CBS scared of or sucking up to the Oval Office?

Today, I called CBS News in an attempt to interview Attkisson. I was told by CBS News senior vice president of communications Sonya McNair that Attkisson would be unavailable for interviews all week. When I asked why Attkisson would be unavailable, McNair would not say.
I've also heard from a producer at another media outlet that has previously booked Attkisson that they tried to book her since she made news with the Laura Ingraham interview yesterday. They were also told that she would be unavailable.

After our initial conversation earlier today, I called McNair back and left a message with her office. I also sent McNair an email asking whether Attkisson's unavailability has anything to do with reporting that the White House and Justice Department were angry at her. I further asked McNair if the White House or Justice Department contacted CBS News about Attkisson since yesterday. McNair has not responded to my inquiries.
From what I've read the CBS brass haven't exactly been enthusiastic about investigating this in the first place; with Attkisson actually acting as a reporter(as opposed to the current examples of 'journalist') they're probably catching heat from the Obama minions for daring to allow someone to really investigate.

Added: this says there are so many requests for interviews that they've told her to just stay on the story for now. Hopefully, that's the case.
