‘Three Republican senators expressed skepticism Sunday about Attorney General Alberto Gonzales's credibility, setting up what one of them called a "make or break" moment for him when he testifies before Congress about his role in firing eight U.S. Attorneys.

"The attorney general has a lot of explaining to do," said Sen. Arlen Specter, R-Pa., the senior Republican on the Senate Judiciary Committee. "Attorney General Gonzales's testimony will be a make or break situation for him."

The committee is scheduled to hear from Gonzales on April 17 - but could move that date forward.

Democrats and a handful of Republicans have voiced concerns that the Bush administration's firing of eight U.S. attorneys last year was rooted in a bid to make the federal law enforcers servants of partisan politics rather than the even-handed rule of law.

While President Bush stands behind Gonzales and resists calls for his resignation, if enough lawmakers turn against him, especially his fellow Republicans, it would be difficult for Gonzales to discharge his responsibilities for lack of confidence in Congress. The Senate Judiciary Committee is the primary panel overseeing the Justice Department.’
