In 2008, the CIA inspector general revealed that the CIA had lied to Congress about the accidental shoot down of American missionaries over Peru in 2001. In 2007, news reports disclosed that the CIA had secretly destroyed videotapes of interrogations of a terrorist suspect.

She would not describe the other incident.

Schakowsky said she thinks Panetta is changing the CIA for the better, adding that the failure to inform Congress was indicative of "contempt" the Bush administration and intelligence agencies under him held for Congress.

"Many times I felt it was an annoyance to them to have to come to us and answer our questions," she said. "There was an impatience and a contempt for the Congress."

The House is expected to take up the 2010 intelligence authorization bill next week. It includes a provision that would require the White House to inform the entire committee about upcoming covert operations rather than just the "Gang of Eight"— the senior members from both parties on the House and Senate Intelligence Committees and the Democratic and Republican leaders in both houses.

The White House this week threatened to veto the final version of the bill if it includes that provision.

Democratic aides said the language may be softened in negotiations with the Senate to address the White House's concern.

But Schakowsky said the wider briefings are the best remedy to avoiding future notification abuses.

Republicans charge that Democratic outrage about the Panetta revelation is just an attempt to provide political cover to House Speaker Nancy Pelosi, who in May accused the CIA of lying to her in 2002 about its use of waterboarding.

What Pelosi knew about the CIA's interrogation program and when she knew it — and why she did not object to it sooner — is expected to be emphasized by Republicans during debate over the intelligence bill.
