It is not possible for Ms Gorelick to both be a witness and and a member of the Commission.
After this op-ed piece she must resign to be able to tell the Commission her side of the story.
Hung by her own petard!
#2 From her 4th March 1995 memorandum: ".....,we believe that it is prudent to establish an act of instructions that will clearly separate the counterintelligence from the more limited, but continued criminal investigations. These procedures, which goes beyond what is legally required, will prevent any risk of creating unwarranted appearances that FISA is being used to avoid procedural safeguards which would apply in a criminal investigation."
Lawyers are excellent at parsing words, but the meaning of this appears quite clear. Also, it would have been her duty to make sure that this memo, if she really wanted to facilitate investigations (/gullibility) was not interpreted in a way not intended by law enforcement agencies.
