Johnson said the Justice Department was blocking the release of the emails.

In a letter to the U.S. National Archives and Records Administration, Johnson, R-Wis., said summer 2016 communications from FBI Special Agent Peter Strzok to FBI Director James Comey's Chief of Staff James Rybicki hinted at the existence of the Clinton-Obama messages that were relevant to the issues raised by her private server. –Fox News

Johnson noted that on June 28, 2016, a week before Comey's public statement declaring that "no reasonable prosecutor" would charge Clinton, embattled former FBI agent Peter Strzok wrote, "Jim – I have the POTUS – HRC emails [Director Comey] requested at end of briefing yesterday. I hesitate to leave them, please let me know a convenient time to drop them off."
