1. President Trump called on the Justice Department to investigate who wrote an anonymous Op-Ed in The New York Times assailing his administration.

“I would say Jeff should be investigating who the author of that piece was because I really believe it’s national security,” he said on Air Force One, referring to Attorney General Jeff Sessions.

Separately, George Papadopoulos, a former Trump campaign adviser who last year pleaded guilty to lying to the F.B.I., was sentenced to 14 days in jail.
