"It's vital that we protect information that if released could jeopardize national security, but the Justice Department will ensure the privilege is not invoked to hide from the American people information about their government's actions that they have a right to know," Miller said.
Meanwhile, the chairman of the Senate Judiciary Committee is proposing a "truth commission" to investigate abuses of detainees, politically inspired moves at the Justice Department, and other decisions made during the Bush administration.
Senator Patrick Leahy, Democrat of Vermont, said the primary goal of the commission would be to learn the truth rather than prosecute former officials, but said the inquiry should reach far beyond looking for misdeeds at the Justice Department under Bush to include matters of Iraq prewar intelligence and the Defense Department.
Leahy outlined his suggestion for a "truth and reconciliation" commission during a speech at Georgetown University yesterday.
"I'm doing this not to humiliate people or punish people but to get the truth out," he said.
The panel he envisions would be modeled after one that investigated the apartheid regime in South Africa. It would have subpoena power but would not bring criminal charges, he said.
Among the matters Leahy wants investigated by such a commission are: the firings of US attorneys, treatment and torture of terror suspect detainees, and the authorization of warrantless wiretapping.
"Rather than vengeance, we need a fair-minded pursuit of what actually happened" during the Bush administration, Leahy said.
Some Democrats have called for criminal investigations of those who authorized certain controversial tactics in the war on terror. Republicans have countered that such decisions made in the wake of the 2001 terror attacks should not be second-guessed.
Representative Lamar Smith of Texas, the senior Republican on the House Judiciary Committee, said no good purpose can be served by Leahy's suggestion, and called it a political scheme "to unjustly malign former Bush administration officials."
