U.S. Sen. Ken Salazar has joined the roster of Senators urging Alberto Gonzales to resign.

Salazar, D-Denver, has long been considered one of Gonzales' few Democratic allies in Congress, and until today he had declined to join many fellow Democrats and handful of Republicans who have been calling for Gonzales to step down in the wake of a controversy over the firing of federal prosecutors last year.

In a press conference in Denver, Salazar said he has become concerned about a "politicization" of the Department of Justice. He said he spoke to Gonzales and urged him to resign, saying it was "time for the Department of Justice to get a fresh start."

Salazar is hardly a liberal Democrat. He's not only centrist, but a well known compromiser who values bi-partisanship.

I'm beginning to think Gonzales may actually resign. If it wasn't likely, I don't think Salazar would have taken a lead role in this.

Then again, perhaps Salazar, formerly the Attorney General of Colorado, just feels particularly strongly about the job.
