In his indictment, there were references to three reporters. Ali Watkins (NY Times) is believed to be one. Speculation is that NBC and CNN were also involved.
Wolfe's indictment was preceded by a long period of surveillance, under a Grand Jury Warrant from the US Attorney for DC, Jessie Liu. Apparently, years worth of reporters electronic records were seized by the prosecutors - an unusual step.
Wolfe was apparently called in and read the riot act in December of 2017, and resigned. He was not publicly indicted until six months later, while presumably investigation continued.
Investigators/Prosecutors could have a lot ready to drop by now, given the lead times. The next few weeks would be a good time, given the election and all.
