“My committee will be the main obstacle between the Biden socialist agenda and the U.S. Constitution,” Comer told the rowdy crowd in his thick Appalachian drawl.

It’s easy to see why the self-described “redneck” chair-in-waiting has charmed many on the Hill. He’s long been known on both sides of the aisle as a sharp and affable colleague, and has the tendency to lean in with a hushed voice, almost conspiratorially, only to crack a well-timed joke that’s often at his own expense. Beyond that personal appeal, though, Comer emphasized it’s his priority to ensure the oversight panel’s work remains “credible.”

That’s a tricky path to tread, given his party’s investigative priorities are still subject to the whims of former President Donald Trump as well as an increasingly zealous conservative base and media apparatus. But Comer’s particularly well-suited to the task, according to more than two dozen House Republicans interviewed. And if he manages to do it right, it could provide a launching pad to higher office — Comer is not discounting a future bid for Senate or Kentucky governor, though that likely wouldn’t occur until after his four remaining years leading the panel.
