Dr. Hotez, a staunch COVID-19 vaccine advocate, heavily criticized Joe Rogan for having anti-vaxxer Robert F. Kennedy Jr. on his popular podcast, and has subsequently rebuffed challenges to participate in a public debate with the presidential candidate.

Rodgers — also notably a skeptic of the COVID-19 vaccines — has previously made it known he's supporting RFK Jr.'s candidacy for president, and on his Instagram Story on Tuesday Rodgers took a shot at Dr. Hotez.

Overlaid above a reel in which Dr. Hotez had previously appeared on Rogan's podcast and admitted to not being "as cautious with my diet as I should be," Rodgers wrote "@robertfkennedyjr would mop this bum."
