That was my point. That the previous administration authorized its use. And the only reason, at the end of the term, to suddenly issue a warning would be because they found people using it wrongly. To cover their own asses. It's amazing how you can't read between the lines.
Yup.
So... nothing supporting your position.
Unless your position is "other people used Signal, too"?
That would be silly, though, since it would mean you think "someone in the government ever used signal" is the important issue.
You are Obtuse again and failing to come up with something. Just arguing for arguing sake. You take everything at face value when it comes from a Democrat.
