President Donald Trump named foreign policy adviser and loyalist Richard Grenell interim executive director of the Kennedy Center on Monday, days after appointing himself chair, solidifying his control over the iconic American cultural institution.

Trump announced former acting DNI director Richard Grenell would lead the Kennedy Center. Board members received termination letters and their names were removed from the center’s website Monday.

President Donald Trump said Monday he is naming Ric Grenell, a longtime confidant already serving in multiple administration positions, to lead the Kennedy Center for the Performing Arts on a temporary basis after declaring himself the institution’s chairman late last week.
