Friends turned foes, podcasters Ben Shapiro and Tucker Carlson took to the stage at Turning Point USA’s America Fest on Thursday night, headlining the event.

Shapiro and Carlson, once Republican political allies, have grown apart in recent months, with each criticizing the other’s views, actions, and words on their respective podcasts. Infighting among those considered among the leaders of the conservative political movement has dominated headlines since the assassination of Turning Point USA Founder and CEO Charlie Kirk. Shapiro and Carlson, along with fellow podcasters Candace Owens, Megyn Kelly, and, to a lesser extent, Tim Pool, have been at the forefront of the controversies.
