After months of resistance, the Bush administration has agreed to brief all members of the House and Senate intelligence committees on its domestic wiretapping program. Analysts said the decision was made to shore up support for CIA nominee Gen. Michael Hayden, who oversaw the National Security Agency when the program was introduced. Hayden’s confirmation hearings begin Thursday. Republican strategists cited another benefit. Because of congressional rules over classified information, lawmakers would be forced to temper public discussion of the program once they were briefed on it. One senior Republican aide told the Los Angeles Times: “When they know about it, they are obligated to be quiet.”
