 That's Fox's Shannon Breen. The RNC begins tomorrow and will last for four days. President Biden tonight making a plea to the nation to stop the talk of violence that he says has infected political speech in America and may have led to the assassination attempt. The president asking Americans not to jump to conclusions about the shooter or possible accomplices. We do not know the motive of the shooter yet. We don't know his opinions or affiliations. We don't know whether he had help or support.
