The 46-year old French national is claiming that Saudi Embassy officials were involved in a plot to shoot down Air Force One to assassinate Bill Clinton and/or Hillary Clinton during a trip to the United Kingdom.
Moussaoui says he met with a Secret Service agent several months ago and told him what he knew. CNN has reached out to the Secret Service for comment.
In two handwritten letters filed this month in federal court in New York and Oklahoma, Moussaoui claimed that, during the time he was taking flying lessons in Norman, Oklahoma, he met with a Saudi prince and princess and that she "gave me money," and provided funding for 9/11 hijackers.
Lawyers for the Saudi government have repeatedly denied connections, maintaining Saudi Arabia was cleared by the 9/11 Commission.
Moussaoui, who suffers from mental illness, is in the supermax federal prison in Florence, Colorado, and is eight years into a life sentence, having pleaded guilty to terrorism and murder conspiracy in connection with the September 11, 2001, terror hijackings.
Report informs, Moussaoui claims in both letters that he was attacked in prison on orders of terrorist Ramzi Yousef, who Moussaoui says tried to stop him from testifying against the Saudis.
Yousef, a convicted terrorist, is considered the mastermind in the 1993 World Trade Center bombing, and is in the same supermax prison as Moussaoui.
It is unclear at this time if prisoners in the Colorado federal prison are able to communicate.
Moussaoui claims he is being mistreated by prison officials in what he calls a "campaign of harassment and intimidation." Citing "venue" issues, Oklahoma Magistrate Judge Shon T Erwin ruled to dismiss the case of Zacarias Moussaoui v. Federal Bureau of Prisons.
The court also denied a request for appointment of counsel.
A ruling is not yet available with regard to the letter he sent to a New York judge.
In the letters, Moussaoui asks for new lawyers and says he wants to be moved out of the H-unit within the prison, which he calls a "Saudi stronghold." In exchange he says he would provide information against the Saudis. He also says he wants a warmer cell, not infested with rodents. He wants authorities to unblock his source to money so he can buy stamps to write to the inspector general.
