This week on "Face the Nation," Congress tries to rescue a breakthrough border security compromise from the pull of election-year politics. We'll talk to Oklahoma Sen. James Lankford, the top GOP negotiator, and Virginia Democratic Sen. Tim Kaine, who's hoping an agreement will also clear the way for more foreign aid to Ukraine and Israel. Plus, we'll check in with Biden administration envoy Amos Hochstein and UAW President Shawn Fain.
