Attorney General William Barr leveled blistering criticism at how the Russia investigation was conducted, saying Tuesday that it was based on a “bogus narrative” that the Trump campaign might have conspired with Russia during the 2016 presidential election. Barr spoke to NBC News one day 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 that there was a proper basis for opening the probe and that it was free of political bias.
