Norm Eisen, the Constitutional lawyer who served as House counsel in the first impeachment trial of President Donald Trump, said he lives by three rules his immigrant parents taught him: always be loyal, always do the right thing no matter the cost, and always serve the best hamburger you can. His immigrant parents ran a hamburger stand in South Los Angeles, and Eisen grew up working there. As Trump’s second impeachment trial opens in the Senate, Eisen, a senior fellow at the Brookings Institution, said in an interview that he believes the rerun is worth it, no matter the cost, though he described the move as “Kantian, not utilitarian.”
