The Trump administration’s Justice Department got telephone records and attempted to get the email records of three Washington Post reporters who were looking into Russian interference in the 2016 presidential election, the newspaper reported on Friday.

The three reporters, Ellen Nakashima, Greg Miller and Adam Entous, who now works for the New Yorker, were informed of the inquiry earlier this week in letters from the department, the Post said, adding that the records were from calls made on work, home and mobile phones from April 15 to July 31, 2017.

The letters, according to the Post, did not say when the department approved the move to get the records, but a department spokesman told the paper that it occurred last year, when William Barr was attorney general. The letters also did not say why the Justice Department sought the records.
