Investigators said Moussaoui attended mosques in Great Britain with suspected al Qaeda connections. One of those mosques was where convicted terrorist cleric Abu Hamza al-Masri was the prayer leader.
After a mental health evaluation, the judge allows Moussaoui to represent himself, only to end his pro-se representation when his filings are cited as "inflammatory and unprofessional."
Moussaoui has stated in court that he belongs to al Qaeda and is loyal to Osama bin Laden.
Prosecutors alleged that Moussaoui attended a terrorist training camp in Afghanistan in 1998.
A search of Moussaoui's belongings shortly after 9/11 turned up Boeing 747 flight manuals, two knives, an aviation radio, information on aerial application of pesticides, and a notebook containing German telephone numbers.
1996 - French authorities begin monitoring Moussaoui when they notice him with Islamic extremists.
1999 - French authorities place Moussaoui on a watch list.
September 2000 - Moussaoui visits Malaysia and stays in the same condo where two of the September 11 hijackers stayed in January 2000.
February 26-May 29, 2001 - Moussaoui trains at the Airman Flight School in Norman, Oklahoma. He takes more than 50 hours of flying lessons but leaves without a pilot's license.
August 1 and 3, 2001 - Moussaoui is allegedly wired $14,000 from Ramzi bin al-Shibh, an alleged al Qaeda operative. The money is wired from Dusseldorf and Hamburg, Germany.
August 16, 2001 - Moussaoui is arrested in Minnesota on immigration issues. The Minneapolis FBI was alerted to Moussaoui after he aroused suspicions at the Pan Am International Flight Academy. Pan Am considered Moussaoui suspicious because he had no prior aviation experience, paid in cash, and only wanted to learn how to take off and land the plane.
August 2001 - Minnesota FBI agents are refused permission by the Washington office to obtain a search warrant for Moussaoui's computer.
September 2001 - Moussaoui is identified as a possible 9/11 conspirator and potential fifth hijacker on Flight 93, the only plane with four instead of five hijackers. Also, the US government states that he was to have piloted a fifth jetliner that would have targeted the White House.
December 11, 2001 - A federal grand jury indicts Moussaoui on six counts of conspiracy related to the September 11 attacks, including conspiracy to destroy aircraft and murder United States employees.
January 2, 2002 - Moussaoui is arraigned. He declines to enter a plea for himself, writing "In the name of Allah, I do not have anything to plead." US District Judge Leonie Brinkema enters a not guilty plea on his behalf.
June 25, 2002 - At the arraignment for a superseding indictment with amended charges, Moussaoui again refuses to enter a plea, and then tries to plead "no contest." Again, the judge refuses to accept the plea, believing Moussaoui does not understand the law, and enters a not guilty plea on his behalf. A month later, a second superseding indictment against Moussaoui is filed, with adjustments to make him eligible for the death penalty.
September 24, 2002 - Prosecutors file a motion that says a business card that belonged to alleged lead hijacker Ziad Jarrah was found in the Shanksville, Pennsylvania, field where UA Flight 93 crashed.

October 2, 2003 - The judge rules that the government will not be able to present evidence that Moussaoui had advance knowledge of or participated in the attacks.

Brinkema also strikes the death penalty from the indictment, and stays the order pending an appeals court review.
