According to court records, Aldawsari conducted online research into how to construct an improvised explosive device, or IED, using several chemicals as ingredients. He has also "acquired or taken a substantial step toward acquiring most of the ingredients and equipment" needed for the bomb, documents said.
Authorities said Aldawsari described his desire for violent jihad and martyrdom in blog postings and a personal journal.
Aldawsari conducted research on various targets and e-mailed himself information on these locations and people, the Justice Department said.
On February 6, the affidavit alleges, Aldawsari sent himself an email titled "Tyrant's House," in which he listed the Dallas address for former President George W. Bush, investigators said.
In a personal journal found in Aldawsari's apartment home, Aldawsari wrote the events of September 11, 2001, had produced a "big change" in his thinking and that he had been inspired by the speeches of Osama bin Laden, the affidavit said. He had excelled in high school in order to take advantage of scholarship opportunities offered by Saudi companies to get to the United States, he wrote, and had been planning to commit a terrorist attack in the United States for years, according to the affidavit.
Aldawsari allegedly wrote the scholarship "will help tremendously in providing me with the support I need for Jihad." The entry continued: "And now, after mastering the English language, learning how to build explosives and continuous planning to target the infidel Americans, it is time for Jihad," the affidavit says.
