Source: House Investigating Whether Eric Holder Lied in Testimony

Specifically, in a May 17 hearing in response to a question about government surveillance of journalists

The House Judiciary Committee is investigating whether Attorney General Eric Holder lied under oath during his May 15 testimony on the Justice Department's (DOJ) surveillance of reporters, an aide close to the matter told The Hill.

The panel is looking at a statement Holder made during a back and forth with Rep. Hank Johnson (D-Ga.) about whether the DOJ could prosecute reporters under the Espionage Act of 1917.
