With Attorney General Alberto Gonzales vowing to remain in his job and President Bush standing by him, Senate Democratic leaders are seriously considering bringing a resolution to the floor expressing no confidence in Gonzales, according to a senior leadership source.

"I don't think [Gonzales] can survive, no matter what the president says," said the source. The vote would be nonbinding and have no substantive impact, but it would force all Republican Senators into the politically uncomfortable position of saying publicly whether they continue to support Gonzales in the wake of the scandal surrounding the firings of eight U.S. attorneys. Democratic leaders have not yet set an exact time frame for when they would bring such a resolution to the floor.
