By Alexander J Martin, technology reporter Facebook has disrupted a disinformation campaign targeting the US midterm elections first detected by American law enforcement. The disinformation campaign appears as if it could be tied to the same Russian company that has been charged with interfering in the 2016 presidential election, although Facebook's investigation is ongoing. In a statement published the night before polls opened, the company said it had been contacted by the police about suspicious behaviour believed to be linked to foreign entities.Facebook said it was revealing the details of the campaign before it had all of the facts due to how soon the polls open.
