I agree with nita, get that information to as many people as possible by secure means.
Possibly some outside of the US. We need God's help for her to know who to trust and who can effectively use the info, who is not a traitor or compromised.
We also need to pray for many within CIA and NSA who are believers to gain courage for such a time as this to stand up and speak truth against the evil wicked in this land.
I'm praying these Psalms :
Psalm 36
Psalm 37
One more thing about snail mail... Hand write everything involving who gets copies. Do not use a computer, phone, etc to discuss it with recipients. Write a handwritten letter to any and all ppl you send evidence to, with explicit instructions to never mention it on a phone, in email or text message, etc. When mailing, drop them in a drive-by mailbox instead of walking into a post office.
You must assume any digital communication whatsoever is not secure, including copiers and printers. To make a copy of handwritten correspondence, use carbon paper, which is still available at office supply stores. Oh, and buy a lot of it, and press down hard. Lol.
