The former speaker is the latest Republican to break ranks with the administration, which still stands behind the attorney general.
Former House Speaker Newt Gingrich on Sunday urged Atty. Gen. Alberto R. Gonzales to resign, saying the "self-created mess" over the firings of eight U.S. attorneys last year had hampered his ability to do his job.
"I cannot imagine how he is going to be effective for the rest of this administration," Gingrich said on "Fox News Sunday." "They're going to be involved in endless hearings, which is going to take up an immense amount of time and effort.
"I think the country, in fact, would be much better served to have a new team at the Justice Department, across the board," he said.
