If Maxine knew about it, and she told all of us she did, then EVERY DEMOCRAT IN CONGRESS AND THEIR AIDES KNEW IT AS WELL................
Maxine isn’t going to spill the beans until they have the Donald in a corner. Her problem will be if she exposes anything EVERYONE will wonder why someone with a low-end clearance has any TS info at all..
And I suspect many Republicans knew, also. Remember Nunes said he was aware of the unmasking well before he spoke out on this subject.
