Gonzales losing support

Key Republicans are abandoning support for Attorney General Alberto Gonzales:

Three key Republican senators sharply questioned his truthfulness over the firings last fall of eight federal prosecutors. Two more Democrats on Sunday joined the list of lawmakers calling for Gonzales' ouster.

Several Republicans also urged President Bush to allow sworn testimony from his top aides about their role in dismissing the U.S. attorneys — a standoff threatening to result in Capitol Hill subpoenas of White House officials.

Gonzales faces the toughest test of his two-year tenure at the Justice Department with the release of documents suggesting he was more involved with the firings than he indicated earlier.
