Wasn’t there an issue with DHS trying to hack Georgia’s election database in 2016? That is why they waited so long in the evening to declare Trump the winner. That’s what I recall.
Later it turned out that they were targeting multiple states. Their excuse was that they were testing the systems to see if foreign actors could get in, or some such nonsense, but they were up to some bad stuff.
We have some at FR who are reassuring us that our team is on top of all of it this time, but after the 2018 ballot harvesting debacle, I’m not convinced until I see it.
