The United States is reportedly weighing whether or not to reject the French government’s selection for its next ambassador to Washington, D.C., as the two countries feud over human rights.

Aurelien ​Lechevallier, the French foreign ministry chief of staff, was selected by President Emmanuel Macron to be the nation’s next ambassador to the U.S., with the hope he would take up the position by September. But sources inside the State Department now claim, according to Reuters, that a brewing feud at the United Nations jeopardizes that appointment.
