The article “WSJ’s Riley: Make the U.S. borderless” contained several errors. Max Boot, senior fellow of the Council on Foreign Relations, said the journalist Jason Riley’s views should make even die-hard xenophobes think twice; that comment was mistakenly attributed to Riley himself. In addition, a quotation attributed to one attendee of his talk, Steve Heller, should have been attributed to audience member Miriam Chirico, and the quotation attributed to Chirico should have been attributed to Heller.
