Just sayin'...
When I had to work with the boys in Langley, it was an SSBI investigation, TS-SCI access, and lifestyles polygraph before getting read in to my program.
Suppose Google requires the same?
BTW, those "leakers" are more often than not Senate staffers and their bosses.
We got tired of it after a while, and came up with a trick. I actually worded each outbound report from my unit slightly differently, knowing which routing those individual reports took inside the Beltline, and we used that via CNN to find out who leaked what.
What really got our dander up was that elected officials do not undergo security clearance checks prior to joining committees with access to sensitive programs. They get briefings from the 3-letter agencies, and then blab to their little heart's content. The info is just something they can leverage for political gain, not unlike a UN demarche.
Go figure.
