He’s talking about Levin.
I was getting a bit bored over the past few months with Levin taking jabs at Savage. Levin even referred to that day's content of Savage's show. I do not know behind the scenes but I wondered what was Levin's issue? I recall Levin intimating months ago that he'd been asked to not continue his battle with that other host.
To the best of my recollection until today Savage has not referred to Levin in a negative manner for a year or more.
