 THE PRESIDENT WAS BRIEFED IN THE SITUATION ROOM BY HIS NATIONAL SECURITY TEAM THIS AFTERNOON. HE SAID HE HAS INSTRUCTED THE FBI TO BE THOROUGH AND SWIFT AS IT INVESTIGATES THE SHOOTER. I URGE EVERYONE, EVERYONE PLEASE, DON'T MAKE ASSUMPTIONS ABOUT HIS MOTIVES OR HIS AFFILIATIONS. LET THE FBI DO THEIR JOB.
