I hope this is accurate. The leftist media is dead silent on it so I'm taking that as a good sign. Townhall, Breitbart and Gateway Pundit have reported on this. Fox mentioned it but seemed to be waiting for details and confirmation. I hope Jeff Sessions has a field day with them.
An intriguing scoop courtesy of OANN's Trey Yingst: Apparently three White House staffers have been caught as the sources of leaked classified info, and "multiple people" are going to be fired when President Trump returns to the United States on May 27 following his first foreign trip.

Per Yingst, the reason for the delay in firing is that names of the leakers are being run by the Office of Government Ethics.
