text:  In a brief televised statement from the White House, President Biden said the motive of the gunman remained unknown and urged people not to speculate. 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.
