It appears to be. Cutter had been posting quite regularly on Twitter, but after her lie about not knowing about the story of the man who accused Romney of killing his wife came to light, her Twitter feed went silent for several hours (upwards of 20, I think).
Now comes word that Cutter's upcoming appearance on This Week has been cancelled.
It's pretty simple. She was caught beyond any doubt or way to weasel out of it and the Obama Administration is trying to hide her and hope the criticism will go away. I refuse to believe that anything she claimed wasn't approved of by Obama and/or his team leaders.
