A former Texas college student from Saudi Arabia was sentenced to life in prison Tuesday for trying to make a bomb for use in a religious attack, possibly targeting a former U.S. president.

Khalid Ali-M Aldawsari was sentenced in Amarillo, where jurors convicted him in June of attempting to use a weapon of mass destruction. Prosecutors say he had collected bomb-making material in his apartment and researched possible targets, including the Dallas home of former President George W. Bush.
