In the category of stories Hersh did not report at the time is a disturbing account from a few weeks after Nixon resigned in 1974 and returned to California. Hersh writes that he had received a tip that Nixon had beaten his wife Pat so badly that she had to be treated at a local emergency room. Then John Ehrlichman, who’d been one of Nixon’s top aides, told Hersh that he knew of other incidents when Nixon had abused her. But Hersh did not report it, or even mention it to his editors, because he believed it would only qualify as news if he could demonstrate that Nixon’s behavior had affected government policy. Hersh later spoke about the story in public in 1998. Women in the audience, he writes, immediately informed him of just how illegitimate and dangerous this standard was.
