text:  And we're going to continue to be brief. The FBI is leading this investigation, which is still in its early stages. We don't yet have any information about the motive of the shooter. We know who he is. I urge everyone, everyone, please, don't make assumptions about his motives or his affiliations. Let the FBI do their job and their partner agencies do their job. I'm instructed that this investigation be thorough and swift. And the investigators will have every resource they need to get this done.
