In Washington, D.C., newly published video shows Turkish President Recep Tayyip Erdogan looking on as members of his security detail assaulted a group of peaceful protesters outside the Turkish ambassador’s residence. Tuesday’s violence left nine anti-Erdogan protesters hospitalized. It’s not clear if Erdogan gave the order for the attack. Among those assaulted were American Diplomatic Security officers assigned to protect Erdogan’s delegation. Police briefly detained the assailants but released them after learning they held diplomatic immunity. The assault came shortly after Erdogan was welcomed to the White House by President Trump. During the meeting, Trump did not mention Turkey’s deteriorating human rights situation, which has seen nearly 50,000 people and 150 journalists arrested since a failed coup last summer.
