WASHINGTON - In the immediate aftermath of the 2001 anthrax attacks, White House officials repeatedly pressed FBI Director Robert Mueller to prove it was a second-wave assault by Al Qaeda, but investigators ruled that out, the Daily News has learned.

After the Oct. 5, 2001, death from anthrax exposure of Sun photo editor Robert Stevens, Mueller was "beaten up" during President Bush's morning intelligence briefings for not producing proof the killer spores were the handiwork of terrorist mastermind Osama Bin Laden, according to a former aide.

"They really wanted to blame somebody in the Middle East," the retired senior FBI official told The News.

On October 15, 2001, President Bush said, "There may be some possible link" to Bin Laden, adding, "I wouldn't put it past him." Vice President Cheney also said Bin Laden's henchmen were trained "how to deploy and use these kinds of substances, so you start to piece it all together."

But by then the FBI already knew anthrax spilling out of letters addressed to media outlets and to a U.S. senator was a military strain of the bioweapon. "Very quickly [Fort Detrick, Md., experts] told us this was not something some guy in a cave could come up with," the ex-FBI official said. "They couldn't go from box cutters one week to weapons-grade anthrax the next."
