(CNN) A former U.S. Army enlistee who vowed to "bring the Islamic State straight to your doorstep" pleaded guilty Wednesday to attempting to detonate a car bomb at Fort Riley military base in Kansas, authorities said.
John T. Booker Jr., 21, an American citizen also known as Mohammed Abdullah Hassan, entered his plea before U.S. District Judge Carlos Murguia to one count of attempted use of a weapon of mass destruction and one count of attempted destruction of government property by fire or explosion, according to a statement from the U.S. Justice Department. He's to receive a 30-year federal prison sentence.
"John Booker admitted that he intended to kill U.S. military personnel on American soil in the name of ISIL," John Carlin, assistant attorney general for national security, said in a statement, referring to the terror organization also known as ISIS.
