U.S. cluster munitions have arrived in Ukraine, after lawmakers in both parties attempted to block President Joe Biden from sending them. Retired four-star Army General Barry McCaffrey joins Andrea Mitchell to discuss. “I think President Biden, Lloyd Austin, and Blinken were entirely correct to send them these munitions—not just as a stopgap for unitary warheads, but because they are a very effective tool, and Ukraine is fighting for its survival,” says McCaffrey. » Subscribe to MSNBC: http://on.msnbc.com/SubscribeTomsnbc Follow MSNBC Show Blogs MaddowBlog: https://www.msnbc.com/maddowblog ReidOut Blog: https://www.msnbc.com/reidoutblog MSNBC delivers breaking news, in-depth analysis of politics headlines, as well as commentary and informed perspectives.
