Torie Clarke wrote the book, Lipstick on a Pig.
She was "Maverick" McCain’s press secretary who helped spin the narrative of McCain’s involvement in the Keating 5 savings & loan scandal, in such a way as to keep him from being indicted or going to prison. Instead, he was only criticized by the Senate Ethics Committee for using "poor judgement" and given a slap on the wrist.
BTW, Clarke was also the genius who first came up with the idea of embedding journalists with the troops in Iraq. Her account begins this way:
For weeks, [Charles] Keating had harangued his contacts in the Senate, of which McCain was one, to get federal regulators who were looking into Keating's company, Lincoln Savings & Loan, off his back. Keating was a political supporter and a personal friend of the family as well. The request put McCain in a tough spot: Keating was also Arizona's largest employer; it was reasonable for a senator to look into the matter on behalf of his constituents...
