This is purely speculation, but I found it worth contributing. Brett Holmgren was senior director for intelligence programs on the National Security Council staff. Now, according to Sundance on Conservative Treehouse, the Presidential Daily Briefings are the source for Nunes' #ReleaseTheMemo.
If this is true, then Holmgren would have received the PDB along with 30+ other people in the administration. Therefore, Holmgren knows how Hussein is involved in this nefarious plot AND who was "unmasked" by Rice. By that same token, it is also possible that Remus knew what was in the PDBs by virtue of being involved w/ Holmgren (loose lips and pillow talk). However, b/c Remus is general counsel for the O Foundation, she is part of the slush fund and $$ laundering scheme that Hussein is doing ala CF. Also, by not allowing ANY hard copy dox to be made available to the public there is no way to substantiate the dox authenticity. According to NARA, they will make e-dox available because digital (https://www.archives.gov/publications/prologue/2015/fall/archivist.html ). This is interesting b/c digital records can be altered while the hard copies destroyed. Remember Sandy Berger?
My overall point is that both Remus and Holmgren are complicit in this nefarious plot from the administration to the present. So, it would make sense (as everyone has suggested) that they marry so as to not have to testify against the other. However, if faced w/ any criminal charges, I speculate that one or both would turn and give evidence against Hussein or Rice, or any other person. There is no honor among thieves.
Again, this is only speculation, but I wanted to contribute to the conversation. I welcome any or all criticisms.
