Memogate, again

Update Here
Sen. Frist’s office wishes to stick with this statement made on the 20th: “I have never seen the memo, I did not authorize the memo, and I condemn the content of the memo and reaffirm that the interest in this case by myself, and the many members of the Senate on both sides of the aisle, is to assure that Mrs. Schiavo has another chance at life.” Who wrote it?
