Following primary losses for high-profile incumbents Thomas Massie and Bill Cassidy, does President Trump’s endorsement remain the GOP's most powerful currency? Former NRSC senior advisor Matt Whitlock joins the Rundown to discuss how this "political machine" could be clearing the field of GOP opposition as we look ahead to the high-stakes Texas Senate runoff between Senator John Cornyn and Ken Paxton. Plus, the question remains: can this primary momentum defeat Democrats in November? As the nation prepares to celebrate its 250th birthday, the upcoming National Memorial Day Concert steps into the spotlight to honor the heavy sacrifices made by servicemembers. Gary Sinise, acclaimed actor, philanthropist, and founder of the Gary Sinise Foundation, joins us to discuss the profound importance of honoring generations of veterans. Sinise shares a personal tribute to his late son, a talented composer whose music will once again soar at the concert, and underscores why we must aggressively preserve firsthand history to ensure future generations never forget the true cost of freedom. PLUS, commentary by Jason Rantz, author of What’s Killing America, and the host of The Jason Rantz Show. PHOTO CREDIT: ASSOCIATED PRESS Learn more about your ad choices.
