Rubio hits it out of the park on national security as the #1 priority of the federal government and the President needing to know this in depth right away.
He made no real point though, because no candidate can know the situation in-depth unless they become president elect and start receiving classified national security briefings.
Somehow, I don’t trust Rubio. He seems too “slick” for me. He seems to not get that our biggest problem by far is the mostly unconstitutional $4 trillion federal government.
