Renaissance Partner Airs Battle With Mercer Over Trump

  • Magerman protests Mercer’s support for Trump as harmful
  • Scientist says he may be fired for speaking out about his boss

A Renaissance Technologies partner went public with his strong objections to top executive Robert Mercer’s support for President Donald Trump, telling the Wall Street Journal of a heated confrontation between the two men that may lead to his firing.

David Magerman has worked at the quantitative hedge fund for 20 years and helped design the firm’s trading systems. A registered Democrat, Magerman, 48, told the paper that Mercer’s “views show contempt for the social safety net that he doesn’t need, but many Americans do.”
