What about President Trumps apparent fix after the uproar . Also, why immigration, why now, why such passion on both sides of the argument . I have a great panel to discuss. And a new arms race in space. This week, President Trump announced a sixth branch of the u. S. Military, a space force. We are going to have the air force and we are going to have the space force.
