Nearly all members of the House of Representatives opted out of a chance to read this year's classified intelligence bill, and then voted on secret provisions they knew almost nothing about. The bill, which passed by 327 to 96 in April, authorized the Bush administration's plans for fighting the war on terrorism. Many members say they faced an untenable choice: Either consent to a review process so secretive that they could never mention anything about it in House debates, under the threat of prosecution, or vote on classified provisions they knew nothing about. Most chose to know nothing. A Globe survey sent to all members of the House, [revealed] the vast majority of the respondents ... said they typically don't read the classified parts of intelligence bills. The failure to read the bill, however, calls into question the vows of many House members to provide greater oversight of intelligence. The rules make open debate on intelligence policy and funding nearly impossible, lawmakers say. Revealing classified secrets has long been a crime, punishable by expulsion from the House and criminal prosecution. Operating largely in secret, the intelligence panels have a limited staff because of the security clearances involved. Further, committee members can't go to outside experts to vet policies or give advice, leaving members with no way to fact-check the administration's assertions. Democratic and Republican leaders are no longer briefed together, raising questions about whether the two leaders are being told the same things.
