Trump calls on Justice Department to investigate anonymous NYT writer

President Trump told reporters on Air Force One that he thinks Attorney General Jeff Sessions should investigate who the anonymous writer of the New York Times op-ed is, claiming it is a national security concern, according to the AP.

The big picture: Trump has already tried to claim that not revealing the identity of the op-ed writer poses a national security concern, although he has yet to specify how. He has also said he considers the act treasonous.
