And a report at New York Times, "Apparently Hacked, a Fox News Twitter Account Sent Out Alarming Posts":
A series of alarming Twitter posts about President Obama appeared on Fox News’ Twitter account for political news early Monday morning, and the Web site for the cable television network said it was a victim of hacking.More details at the link.
The Twitter account, @foxnewspolitics, one of many that is operated by Fox News, claimed that the president died while campaigning in Iowa, but gave no source for the news. On Monday morning, FoxNews.com first posted a brief statement saying that the reports were incorrect, and that it regretted “any distress the false Tweets may have created.”
The six messages — which as of late Monday morning were still available online — created a flurry of attention overnight and senior Secret Service officials were gathering on Monday morning to discuss them, said to a law enforcement official who declined to be identified because of an investigation into the matter.
A spokesman for the Secret Service, George Ogilvie, said, “We’re not commenting on any of this.”
Jeff Misenti, the vice president and general manager of Fox News Digital, said in a later statement on Monday that the news organization will be requesting “a detailed investigation from Twitter about how this occurred, and measures to prevent future unauthorized access into FoxNews.com accounts.”
