This week Twitter challenged the accuracy of President Trump's tweets by adding information to refute his claims. It was the first time the social media platform did something of the sort, after years of getting pressured to act on false posts. Until recently, Jack Dorsey, chief executive of Twitter, had always explained that the company considered that the world should see how global leaders think and refused to delete or alter politician's claims on the platform. However, the warning labels they added to Trump's tweets this week may imply a big shift on how the company will deal with leaders spreading disinformation from now on. This new policy seems to be more in line with what experts advocate for. Joan Donovan, research director at Harvard Kennedy School's Shorenstein Center, said to the New York Times: "If world leaders are not kept to the same standard as everyone else, they wield more power to harass, defame and silence others."
