 Look, Vice President Harris and I were just briefed in the Situation Room by my Homeland Security team, including the Director of the FBI, the Secretary of Homeland Security, the Attorney General, the Director of the Secret Service, my Homeland Security Advisor, the National Security Advisor, and we're going to continue to be briefed. 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.
