In the last week of the 2016 Presidential campaign, Stephen Feinberg, the billionaire Manhattan financier, made the largest political donation of his life. On November 3rd, just five days before the election, he gave nearly a million dollars to Rebuild America Now, the Trump-supporting super packnown for its blistering attacks on Hillary Clinton. That Sunday, the pac spent eight hundred thousand dollars on an eleventh-hour blitz of negative TV spots, including one that aired repeatedly during N.F.L. broadcasts, condemning Clinton’s support for changing the name of the Washington Redskins. “Yeah, you thought you were safe, sitting in your recliner in your man cave, cold beer and a bowl of chips,” the ad said. “Wrong. Hillary Clinton wants to mess up your football, too.” Two days later, Trump won the Presidency.
Feinberg is lean, with a runner’s physique and a mild New York accent. His manner is equanimous, and his focus on the task at hand is intense.
