Abdulazeez kept a blog where he wrote two posts on July 13––just days ago––about his thoughts on Islam.
(His blog has since been deleted.)
Mohammad Youssef Abdulazeez traveled to Jordan last year for seven months.
U.S. authorities are looking into a trip to the Middle East last year by Mohammad Youssuf Abdulazeez, the gunman who killed four Marines in attacks on military centers in Chattanooga, Tennessee.
He left the United States in April, returned in November and traveled through Jordan.
Abdulazeez, 24, was born in Kuwait. The Kuwaiti Interior Ministry said Friday that he was of Jordanian origin.
Abdulazeez may have also traveled to Yemen.
