Who Is Daniel Richman, the Columbia Professor Who Leaked Comey's Trump Memo? - NBC News
Richman said he's sure that politics didn't play a part when Comey decided to re-examine Clinton's emails."When you have an obligation to disclose or to qualify, you do it full-stop," Richman added. "You don't worry about timing, you don't worry about how it will be read or spun by others."
Odds are 80/20 he;s a liberal, just based on the fact he is a law school professor. He is openly a defender of Comey's decision to whitewash Hillary, and would find Rosenstien's legal analysis in the "fire Comey" letter to be incorrect.
His mother in law was the head of Planned Parenthood of Bloomington, Indiana, according to her obituary. But I haven’t looked beyond a few pages of search results. He clerked for Thurgood Marshall according to one thing I found. But maybe that was a different DC Richman.
