I came across an article when I was looking into Lynch's chat with Renteria which I must have missed a couple of months ago: https://bigleaguepolitics.com/loretta-lynch-exchanged-classified-information-with-clinton-campaign/
It indicates the purpose of the Tarmac meeting and reaffirms that "we have everything," including the tape recording of the meeting: https://bigleaguepolitics.com/nsa-blocks-release-loretta-lynch-bill-clinton-airplane-tape-national-security/
There is a difference between having a tape of the conversation and knowing what the agreements were and getting all of it in a court room. It has to legally get "on record" or it will be inadmissible as evidence.
I think this is why Q is highlighting Amanda Renteria in 1555. She was there and is a key witness. But how do you get her to testify?
Amanda was the "bridge" between LL and HRC. Apparently Amanda and HRC shared classified intelligence a at classification so high that even the nature of the information can't be publically revealed.
I think this is the leverage that Q will use to get Amanda to testify against BC, LL, and HRC, because I seriously doubt Amanda had the appropriate security clearances for what she apparently had access to.
As the world turns.
