On this episode of The Federalist Radio Hour, Lt. Gen. H.R. McMaster, former Trump National Security Advisor, joins Host Ben Domenech for a conversation about his new book, “Battlegrounds: The Fight to Defend the Free World.” McMaster details his time in the White House and some of the policy initiatives made concerning China, Russia, and other countries.
