The Associated Press, which declared Hillary Clinton the presumptive Democratic presidential nominee a day before the final primaries, told its reporters to “practice situational awareness” after harassment from angry Bernie Sanders supporters. “Some AP staff have received angry communications in the form of emails, social-media messages, and phone calls,” the press cooperative’s vice president for global security said. “We have not received any specific security threats.” Reporters at TheWashington Post, New York Times, and National Public Radio have said they were personally attacked and even threatened by Sanders supporters, too.
