Hunter Biden reemerged this summer with a steady social media and podcast presence, and he’s heading into the fall with a new gig: writer.

On Wednesday, the son of former President Joe Biden announced that he’s joined Substack, the online self-publishing platform favored by independent journalists, pundits, and other media figures. Biden’s column will be titled “Where’s Hunter?,” a tongue-in-cheek nod to an ad-lib President Donald Trump debuted on the 2020 campaign trail while facing off against the elder Biden.
