Sen. Diane Feinstein warned Cheney's office on Sept 10, 2001

[HamdenRice]

I'm not sure whether others are aware of this, but according to CNN Sen. Diane Feinstein, in her capacity as member of the Senate Intelligence Committee was worried about an impending terrorist attack on the United States. On September 10, 2001, she contacted the office of Vice President Cheney to urge a restructuring of federal counter-terrorism efforts.

Cheney's office responded that it would take six months for them to prepare for a meeting with her.

Thanks to the Real History blog for bringing this to my attention.

SEPTEMBER 10, 2001
A CIA plan to strike at al Qaeda in Afghanistan, including support for the anti-Taliban Northern Alliance, is given to the White House. Sen. Dianne Feinstein asks for a meeting with Vice President Dick Cheney. The California Democrat is told that Cheney's staff would need six months to prepare for a meeting

What I said last July on CNN was that I was deeply concerned as to whether our house was in order to prevent a terrorist attack. My work on the Intelligence Committee and as chair of the Technology and Terrorism Subcommittee had given me a sense of foreboding for some time. I had no specific data leading to a possible attack.

In fact, I was so concerned that I contacted Vice President Cheney's office that same month to urge that he restructure our counter-terrorism and homeland defense programs to ensure better accountability and prevent important intelligence information from slipping through the cracks.

Despite repeated efforts by myself and staff, the White House did not address my request. I followed this up last September 2001 before the attacks and was told by 'Scooter' Libby that it might be another six months before he would be able to review the material. I told him I did not believe we had six months to wait.
