These kinds of tragedies [like shooting in Fort Lauderdale] have happened too often during the eight years that I've been president. The pain, the grief, the shock that they must be going through is enormous. I've asked me staff to reach out to the mayor down there and make sure that coordination between the state and local officials is what it should be. But I think we'll find out over the next 24 hours exactly how this happened and what motivated this individual.
