This week on Face The Nation, a USF-22 shoots down a third unidentified aerial object in the skies over northwestern Canada. And fighter jets are scrambled following a curious radar signal over Montana. What are these incursions all about? We'll talk with two key lawmakers, House Foreign Affairs Committee Chairman Michael McCall and Senator John Tester. Plus, we heard the presidents take on the state of the Union, but as the nation's governors convene in Washington, we'll check in with four of them on the challenges that they're facing.
