Washington, D.C. ? Newt Gingrich on Sunday became the latest prominent Republican to paint a bull’s-eye on President Bush’s embattled attorney general, Alberto Gonzales.

The nation’s top lawman has become a political dartboard since the Justice Department and White House fired eight U.S. attorneys, then gave varying explanations for the dismissals.

Three top Justice Department officials have quit in the furor, and Sunday, Gingrich said they all should go.

“This has been so mismanaged that I think they need an entire new team at Justice,” the former House speaker, a potential 2008 candidate, said after a TV appearance.

“The public would be much better served to have another attorney general,” Gingrich said earlier on “Fox News Sunday,” noting that Gonzales and other top officials at the Justice Department will be tied up in congressional hearings over the firings.

“I cannot imagine how he is going to be effective for the rest of this administration,” the ex-Georgia congressman said.

Gonzales is set to testify next week before the Senate Judiciary Committee.
