WASHINGTON (AP) — Attorney General William Barr is leveling blistering criticism at how the Russia investigation was conducted. He says it was based on a “bogus narrative” that the Trump campaign might have conspired with Russia during the 2016  election. Barr spoke to NBC News after the release of a Justice Department inspector general report that found problems with the FBI’s investigation into ties between the Trump campaign and Russia, but also concluded there was a proper basis for opening the probe. Barr said he disagreed with the inspector general that the FBI had enough information to open the probe and particularly to use surveillance on a former Trump campaign aide.
