I was searching high and low for this, but Ratherbiased beat me to it. Mary Murphy, as one of our visitors mentioned in the comments, reached an agreement with CBS and resigned today:

“CBS News and I have reached an amicable resolution, and I have resigned my position,” Murphy said in a statement.

She said she wished “my good colleagues well” and looked forward to moving on in her career.

That leaves Josh Howard and Betsy West, who were both asked to resign after the Memogate investigation but have yet to do so.
