WASHINGTON (CNN) -- Embattled U.S. Attorney General Alberto Gonzales has resigned, senior administration officials told CNN Monday.

President Bush will likely nominate Homeland Security Secretary Michael Chertoff to the position, senior administration officials said. Clay Johnson, deputy director for management at the Office of Management and Budget, would replace Chertoff, the officials said.

Many lawmakers from both sides of the aisle have long called for his ouster after the firing of several U.S. attorneys in 2006. Bush had long stood by Gonzales.
