A Saudi man who came to the United States on a student visa has been sentenced to life in prison for attempting to make a bomb as part of a plot that may have targeted former U.S. President George W. Bush.

The Justice Department says Khalid Ali-M Aldawsari was sentenced Tuesday, after being convicted of attempting to use a weapon of mass destruction.  

Investigators say he purchased chemicals and equipment to make an explosive device and researched potential U.S. targets.

Aldawsari entered the U.S. in 2008 and took classes at a college near Lubbock, Texas.  Assistant Attorney General Lisa Monaco says Aldawsari came to the U.S. "intent on carrying out an attack."

Authorities say he allegedly described a desire for a violent "jihad" or holy war in blog posts and a personal journal.  They also say he sent himself an email, titled "Tyrant's House," that included the address for former President Bush's Texas home.

Authorities arrested Aldawsari in February 2011, after tracking his online activities and searching his apartment.
