Monica Goodling is the second member of Gonzales' senior staff to quit in the scandal over the firing of eight U.S. attorneys. Goodling, a senior counselor to Gonzales, worked with Kyle Sampson, who was the attorney general's chief of staff, on deciding who to fire.
Goodling submitted a brief letter to Gonzales announcing her departure, the Washington Post reported.
Sampson and Goodling also worked together to brief Deputy Attorney General Paul McNulty before his testimony to the Judiciary Committee. McNulty complained about being given inaccurate information, something cited by Goodling when she invoked her constitutional right to avoid self-incrimination.
