Donald Trump Jr. bantered on social media with billionaire Elon Musk and influential podcaster Joe Rogan over which MSNBC shows they’d host if Musk — as he mused over the weekend — ends up buying the network. But the posts from President-elect Donald Trump ’s eldest son took a turn when he riffed on MSNBC anchor Lawrence O’Donnell and castration.

Elon Musk has indicated that he may be interested in buying the liberal cable news network MSNBC. Donald Trump Jr. shared a post on X following news that the network’s parent company Comcast is spinning off cable TV channels into a separate company. “Hey @elonmusk I have the funniest idea ever!!!” Trump Jr. wrote.
