President Donald Trump's national security advisor Michael Waltz is expected to step down. This comes after growing frustrations with Waltz after he added a reporter to a Signal chat with top Trump officials that discussed a US military strike on Houthi rebels in Yemen. Trump had repeatedly defended both Waltz and Defense Secretary Pete Hegseth following the Signal incidents. Marco Rubio will act as national security advisor and Waltz is now being nominated for United Nations Ambassador. Marty and Adam discuss how all this played out this morning and what’s next.
