Addington has consistently advocated that under the Constitution, the President has substantial and expansive powers as commander-in-chief during wartime, if need be. He is the legal force behind over 750 signing statements that President George W. Bush issued when signing bills passed by Congress, expanding the practice relative to other Presidents. Charlie Savage, the former national legal affairs writer for "The Boston Globe" who won a Pulitzer Prize for his reporting on signing statements, quotes former associate White House counsel Brad Berenson saying that Addington "would dive into a 200-page bill like it was a four-course meal" as he crafted the statements.
