DES MOINES, Iowa — Senator Clinton yesterday dismissed any comparison between the firing last fall of eight U.S. attorneys with the replacement of 93 U.S. attorneys when her husband became president in 1993.

“That’s a traditional prerogative of an incoming president,” Mrs. Clinton said in an interview with the Associated Press.

Once U.S. attorneys are confirmed, they should be given broad latitude to enforce the law as they see fit, she said.

“I think one of the hallmarks of our democracy is we have a devotion to the rule of law,” Mrs. Clinton said.

She conceded that should she win the presidency in 2008, she likely would replace all of the U.S. attorneys appointed by President Bush. She said that’s merely following traditions in which presidents appoint prosecutors of their own party.

Mrs. Clinton argued that the Bush administration’s firing of the eight federal prosecutors has caused an uproar because it is seen as a conservative push to shift the balance of power in favor of the executive branch.

Democrats have accused the Justice Department and the White House of purging the prosecutors for political reasons. The Bush administration maintains the firings were not improper because U.S. attorneys are political appointees.

Meanwhile, Monica Goodling, a senior Justice Department official involved in the firings of federal prosecutors, will refuse to answer questions at upcoming Senate hearings, citing Fifth Amendment protection against self-incrimination, her lawyer said yesterday.

“The potential for legal jeopardy for Ms. Goodling from even her most truthful and accurate testimony under these circumstances is very real,” said the lawyer, John Dowd.

“One need look no further than the recent circumstances and proceedings involving Lewis Libby,” he said, a reference to the recent conviction of Vice President Cheney’s former chief of staff in the CIA leak case.

The White House, meanwhile, continued to stand by Attorney General Alberto Gonzales despite new calls over the weekend for his resignation and documents that indicate he may have been more involved in the dismissals than he has previously acknowledged.

Ms. Goodling was Mr. Gonzales’s senior counsel and White House liaison until she took a leave of absence earlier this month. She was subpoenaed last week by the Senate Judiciary Committee along with several of Mr. Gonzales’s other top aides. There have been questions about whether Ms. Goodling and others misinformed Deputy Attorney General Paul McNulty about the firings just before he testified before the Senate committee in February.

Mr. Gonzales’s truthfulness about the firings of seven prosecutors on December 7 and another one months earlier also have been questioned. On March 13 at a news conference, Mr. Gonzales denied that he participated in discussions or saw any documents about the firings, despite documents that show he attended a November 27 meeting with senior aides on the topic, where he approved a detailed plan to carry out the dismissals.
