Conservative commentator Dan Bongino has become a powerhouse radio host, with many hailing him as the successor to the late Rush Limbaugh.

Now, Bongino appears poised to flex some serious muscle in opposition to his radio distributor's vaccine mandate:

In late May, the massively influential radio network Westwood One debuted a new daily talk show from Dan Bongino, a former Secret Service agent and New York City cop who gained stature in conservative media during the presidency of Donald Trump...

Within two months, the show had reached distribution on more than 300 stations, which the company described as "impressive growth."

Now, Bongino is threatening to walk away completely. He has taken issue with a vaccination mandate imposed in August by Westwood One's owner, Cumulus Media. Chief executive Mary Berner gave all employees until Sept. 27 to be fully vaccinated against the coronavirus before an expected return to the office and wrote that "it would neither be fair nor do we have the bandwidth to make exceptions based on individual preferences," according to industry publication Inside Radio.

In Bongino's own words:

"I believe these vaccine mandates are unethical. I believe they're immoral. I believe they don't take into account the science of natural immunity due to a prior infection. I believe they're broad-based and don't take into account an individual circumstances of why they may or may not want to take a vaccine. And they're antithetical to everything I believe in."

BONGINO BEAST MODE ACTIVATED.

This is a big deal. There are millions of people and millions of dollars involved. Seriously brave stand here.

This will be one to watch, both in and of itself and for the effect it might have on vaccine mandates in other industries. Stay tuned.
