My guess would have to be that Goodlatte and Gowdy (and possibly Grassley) are the only members of congress with the complete Strzok/Page texts. See Chair+. Gowdy is chair of oversight and IGs report to him. Goodlatte is Chair of the judiciary committee oversees administration of justice and the FBI. I would have to assume that Goodlatte is working on something related to this Trump tweet and overseeing what is going on with Judge Contreras.
