President Bush has ordered all White House staff to attend a new round of ethics briefings in the wake of the indictment of a top aide.

In a memo released Saturday, President Bush told his entire staff to attend the briefings, which will include procedures for handling classified information.

The announcement comes one week after Vice President Dick Cheney's chief of staff, Lewis Libby, was charged with obstruction of justice and perjury. The case involves the leak of the identity of a CIA officer married to a critic of the intelligence leading up to the Iraq war.

In their weekly radio address, Democrats say there are very serious questions about how the Bush administration handled pre-war intelligence. Senator Barbara Mikulski, of the state of Maryland also said Mr. Bush should fire all those involved in the leak of the CIA officer's name.
