Episode 447: Waltz Out, Rubio In: A National Security Shake Up

Today, Martha, Les, and Andrew discuss the sudden removal of National Security Advisor Mike Waltz, who has now been nominated by President Trump to serve as U.S. Ambassador to the United Nations.

What message does this send to allies and adversaries alike? And with Marco Rubio now wearing multiple hats as Secretary of State, acting USAID administrator, and interim National Security Advisor, is this a moment of consolidation—or further chaos?Check out the answers to these questions and more in this episode of Fault Lines. Check out the sources that helped inform our experts today: https://apnews.com/live/donald-trump-news-updates-5-1-2025 https://www.bbc.com/news/live/crkx3ed5dn2t Follow our experts on Twitter: @marthamillerdc@lestermunson@AndrewBoreneLike what we're doing here?  Be sure to rate, review, and subscribe.  And don't forget to follow @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/FTR22P675n0  Hosted on Acast.
