Unbelievable. Some excerpts:
I am writing to reiterate my concern regarding the sensitive intelligence issues we discussed today.
Clearly the activities we discussed raise profound oversight issues. As you know, I am neither a technician or an attorney. Given the security restrictions associated with this information, and my inability to consult staff or counsel, on my own, I feel unable to fully evaluate, much less endorse these activities...
I am retaining a copy of this letter in a sealed letter envelope in the secure spaces of the Senate Intelligence Committee to ensure I have a record of this communication.
