The dude was a highly successful and sought-after Hollywood lawyer for copyright and tech law, gave up his job at a law firm because he didn’t want conflicts of interest, and is now a professor at Georgetown. You don’t need to jam his bro onto him. He was already set, lol.
He also did work for a law firm representing Walmart and Merek. You could ding him for that maybe, I don’t know what he did for either, but to drag his brother into a political fight seems a bit icky.
