The Washington Post says it has uncovered a failed sting operation" by a group trying to peddle a sensational but false story to its journalists. A source told the newspaper she had been impregnated as a teenager by US politician Roy Moore. The Post said its research debunked her story, and that she worked for a group called Project Veritas, which it said "targets the mainstream news media". The group said the Washington Post was reporting "an imagined sting". The Washington Post said it was originally approached by a woman the day after it published allegations that US Senate candidate Roy Moore had once initiated a sexual encounter with a 14-year-old girl. The woman, who used a fake name, claimed to have had a sexual relationship with Mr Moore when she was 15. "She said that she got pregnant, that Moore talked her into an abortion and that he drove her to Mississippi to get it," the newspaper said of the conversations. Project Veritas has posted a series of tweets claiming to expose bias at the Washington Post. It claimed the newspaper was attempting to divert attention by inventing the "sting operation" story. But many journalists on social media claimed the attempt to prove the Washington Post had published unverified claims had backfired - and showed the opposite.
