President Trump has personally pledged to spend one billion dollars if it will keep him in the White House. McKay Coppins, a journalist for The Atlantic, has identified how a substantial amount of this funding is being spent. After creating a Facebook page so he could follow pro-Trump social media accounts and communicate with online Trump supporters, Coppins uncovered something remarkable: a campaign-coordinated effort to undermine journalists and the mainstream press on a mass scale. Coppins told Hari Sreenivasan about the Trump campaign’s stunning effort to launch one of the largest disinformation campaigns ever conducted.
