(CBS) In the aftermath of Sept. 11, President Bush ordered his then top anti-terrorism adviser to look for a link between Iraq and the attacks, despite being told there didn't seem to be one.

The charge comes from the adviser, Richard Clarke, in an exclusive interview on 60 Minutes.

The administration maintains that it cannot find any evidence that the conversation about an Iraq-9/11 tie-in ever took place.

Clarke also tells CBS News Correspondent Lesley Stahl that White House officials were tepid in their response when he urged them months before Sept. 11 to meet to discuss what he saw as a severe threat from al Qaeda.

"Frankly," he said, "I find it outrageous that the president is running for re-election on the grounds that he's done such great things about terrorism. He ignored it. He ignored terrorism for months, when maybe we could have done something to stop 9/11. Maybe. We'll never know."

Clarke went on to say, "I think he's done a terrible job on the war against terrorism."

The No. 2 man on the president's National Security Council, Stephen Hadley, vehemently disagrees. He says Mr. Bush has taken the fight to the terrorists, and is making the U.S. homeland safer.

Clarke says that as early as the day after the attacks, Secretary of Defense Donald Rumsfeld was pushing for retaliatory strikes on Iraq, even though al Qaeda was based in Afghanistan.

Clarke suggests the idea took him so aback, he initally thought Rumsfeld was joking.

Clarke is due to testify this week before the special panel probing whether the attacks were preventable.

His allegations are also made in a book, "Against All Enemies," by Free Press, a subsidiary of Simon & Schuster. Both CBSNews.com and Simon & Schuster are units of Viacom.

Clarke helped shape U.S. policy on terrorism under President Reagan and the first President Bush. He was held over by President Clinton to be his terrorism czar, then held over again by the current President Bush.

In the 60 Minutes interview and the book, Clarke tells what happened behind the scenes at the White House before, during and after Sept. 11.

When the terrorists struck, it was thought the White House would be the next target, so it was evacuated. Clarke was one of only a handful of people who stayed behind. He ran the government's response to the attacks from the Situation Room in the West Wing.

"I kept thinking of the words from 'Apocalypse Now,' the whispered words of Marlon Brando, when he thought about Vietnam. 'The horror. The horror.' Because we knew what was going on in New York. We knew about the bodies flying out of the windows. People falling through the air. We knew that Osama bin Laden had succeeded in bringing horror to the streets of America," he tells Stahl.

After the president returned to the White House on Sept. 11, he and his top advisers, including Clarke, began holding meetings about how to respond and retaliate. As Clarke writes in his book, he expected the administration to focus its military response on Osama bin Laden and al Qaeda. He says he was surprised that the talk quickly turned to Iraq.

"Rumsfeld was saying that we needed to bomb Iraq," Clarke said to Stahl. "And we all said ... no, no. Al-Qaeda is in Afghanistan. We need to bomb Afghanistan. And Rumsfeld said there aren't any good targets in Afghanistan. And there are lots of good targets in Iraq. I said, 'Well, there are lots of good targets in lots of places, but Iraq had nothing to do with it.

"Initially, I thought when he said, 'There aren't enough targets in-- in Afghanistan,' I thought he was joking.

"I think they wanted to believe that there was a connection, but the CIA was sitting there, the FBI was sitting there, I was sitting there saying we've looked at this issue for years. For years we've looked and there's just no connection."

Clarke says he and CIA Director George Tenet told that to Rumsfeld, Secretary of State Colin Powell, and Attorney General John Ashcroft.

Clarke then tells Stahl of being pressured by Mr. Bush.

"The president dragged me into a room with a couple of other people, shut the door, and said, 'I want you to find whether Iraq did this.' Now he never said, 'Make it up.' But the entire conversation left me in absolutely no doubt that George Bush wanted me to come back with a report that said Iraq did this.

"I said, 'Mr. President. We've done this before. We have been looking at this. We looked at it with an open mind. There's no connection.'

"He came back at me and said, "Iraq! Saddam! Find out if there's a connection.' And in a very intimidating way. I mean that we should come back with that answer. We wrote a report."

Clarke continued, "It was a serious look. We got together all the FBI experts, all the CIA experts. We wrote the report. We sent the report out to CIA and found FBI and said, 'Will you sign this report?' They all cleared the report. And we sent it up to the president and it got bounced by the National Security Advisor or Deputy. It got bounced and sent back saying, 'Wrong answer. ... Do it again.'

"I have no idea, to this day, if the president saw it, because after we did it again, it came to the same conclusion. And frankly, I don't think the people around the president show him memos like that. I don't think he sees memos that he doesn't-- wouldn't like the answer."

Clarke was the president's chief adviser on terrorism, yet it wasn't until Sept. 11 that he ever got to brief Mr. Bush on the subject. Clarke says that prior to Sept. 11, the administration didn't take the threat seriously.

"We had a terrorist organization that was going after us! Al Qaeda. That should have been the first item on the agenda. And it was pushed back and back and back for months.
