Sean Duffy, acting administrator of NASA, is defending the agency’s cuts as more than 20% of its employees applied to depart NASA in July through the Trump administration's deferred resignation program. “I think we can do more with less,” Duffy tells CBS News’ Mark Strassmann. “Let’s get the best and brightest people working for us to accomplish missions. And if we can do it with less money, that means I have more money for the moon and Mars, and for our low Earth orbit station.” | CBS News
