Jean-Pierre: Republicans are playing chicken with our national security. If they don't get a hundred percent of their extreme demands, they'll block critical border funding, and kneecap Ukraine on the battlefield, damaging our national security…congress can not let Putin prevail; the stakes are just too high.

John Kirby [White House press conference]: There should be, by everybody…a genuine concern about what happens if you just let Putin go. If you just let him have Ukraine…Putin gets all of Ukraine, then what? Then where's he go? Because right then, he's up against the eastern flank of NATO. And if you think the cost of supporting Ukraine is high now, just imagine how much higher it's gonna be, not just in national treasure, but in American blood, if he starts going after one of our NATO allies…American troops would very much have to be involved if Mr. Putin is let to have a strategic victory in Ukraine, and then perhaps goes after one of our NATO allies.
