Starr didn't back pedal. He was carelessly misquoted all day. He never predicted GOP Senators would ask Trump to resign. The context of his comment was that is what some hope, but based on what we've seen so far that won't happen.
OH? Well that is much better from Starr then.
The issue would be has the MSM misquoted Starr?
Who cleared him, what does unofficially mean, and why should anyone believe him? Does he have a high level of success in his predictions?
