Good point. Also since Bongino is a bit of a loose cannon they might prefer to not have that exposure on the broadcast airwaves.It depends on what deal they made when Bongino left. And if he really wants to do the work of a daily show when the real cash cow is the podcast.
From what I'm reading, Bongino knew the government gig was short term. So I imagine plans were made for some kind of return.
Right now it seems like Cumulus is looking to cut costs for all their shows. So they may not be able to afford Bongino anymore.
