Attorney General Alberto Gonzales is under increasing fire from Democrats on Capitol Hill over the firing of eight US Attorneys around the country. Federal prosecutors, who serve at the pleasure of the President, are supposed to be independent of politics. Last week, two former US attorneys told Congress they felt "leaned on" by Republicans to pursue partisan agendas. Today, Gonzales’s top aide resigned after reports that the White House was deeply involved in the firings. New York’s Democratic Senator, Charles Schumer, called for Gonzales to step down.
