FBI is investigating tweets purportedly from the Pensacola shooting suspect that detail his hatred of the United States. Barely two hours before a Saudi aviation student went on a deadly shooting spree at Naval Air Station Pensacola, tweets purportedly written by the suspect railed against the United States for its support of Israel and for stationing troops at bases in Saudi Arabia. The FBI is working to confirm the tweets came from the suspect, who killed three and wounded eight others Friday morning at the Florida base. Ref. USAToday.
