Another short quote:

Meanwhile, Addington has fought tirelessly to stem reform of other controversial aspects of the New Paradigm, such as the detention and interrogation of terror suspects. Last year, he and Cheney led an unsuccessful campaign to defeat an amendment, proposed by Senator John McCain, to ban the abusive treatment of detainees held by the military or the C.I.A.

On Guantanamo:

In a series of meetings at the White House, Gordon, Bellinger, and other officials warned Addington and Gonzales that potentially innocent people had been locked up in Guantánamo and would be indefinitely. "This is a violation of basic notions of American fairness," Gordon and Bellinger argued. "Isn't that what we're about as a country?" Addington's response, sources familiar with the meetings said, was "These are 'enemy combatants.' Please use that term. They've all been through a screening process. We don't have anything to talk about."

He also is in step with the Administration's passion for secrecy:

"Lip-lock" is the word Addington's old Pentagon colleague Sean O'Keefe, now the chancellor of Louisiana State University, used to describe his discretion. "He's like Cheney," O'Keefe said. "You can't get anything out of him with a crowbar."

Mayer implies he drove other Administration lawyers out:

The Administration lawyer said, "He's a bully, pure and simple." Several talented top lawyers who challenged Addington on important legal matters concerning the war on terror, including Patrick Philbin, James Comey, and Jack Goldsmith, left the Administration under stressful circumstances. Other reform-minded government lawyers who clashed with Addington, including Bellinger and Matthew Waxman, both of whom were at the N.S.C. during Bush's first term, have moved to the State Department.

Addington is the force behind the presidential signing statements:

He reportedly scrutinizes every bill before President Bush signs it, searching for any language that might impinge on Presidential power.

Addington comes off like a cancer in the Administration that kills off even the healthy cells. I do wish Mayer relied less on Bruce Fein as her constitutional authority, and the article is way too long, but if you have the patience, it's well worth the time.
