The Washington Post's Dan Eggen does a wonderful job reporting on this astounding development in "Gonzales Nomination Draws Military Criticism":

A dozen high-ranking retired military officers took the unusual step yesterday of signing a letter to the Senate Judiciary Committee expressing "deep concern" over the nomination of White House counsel Alberto R. Gonzales as attorney general, marking a rare military foray into the debate over a civilian post.

The group includes retired Army Gen. John M. Shalikashvili, former chairman of the Joint Chiefs of Staff. The officers are one of several groups to separately urge the Senate to sharply question Gonzales during a confirmation hearing Thursday about his role in shaping legal policies on torture and interrogation methods.

In addition to Shalikashvili, other prominent signatories to the letter include retired Marine Gen. Joseph P. Hoar, former chief of the Central Command; former Air Force Chief of Staff Merrill A. McPeak; and Lt. Gen. Claudia J. Kennedy, the Army's first female three-star general. Several, including Shalikashvili, supported the failed presidential candidacy of Democrat John F. Kerry.

Richard H. Kohn, a military historian at the University of North Carolina at Chapel Hill who specializes in military-civilian affairs, said the letter is extremely rare, if not unprecedented.

If Gonzales is this despised by a number of the Pentagon brass, I'm not certain he should be the next Attorney General.
