Attorney General Alberto Gonzales has acknowledged mistakes in the firing of eight U.S. attorneys but is refusing calls to step down. This comes as the House Judiciary Committee has released a series of emails and documents showing the White House initiated the process that led to the dismissals. The decisions were made in part on whether the prosecutors “exhibited loyalty to the president and attorney general.” On Capitol Hill, Democratic lawmakers say they want to question White House adviser Karl Rove and former White House counsel Harriet Miers.
