;) always a scandal. When Dems do it.. Politicians of both parties routinely use apps like wickr and signal. often illegally not following records keeping laws.

I know obama had a special blackberry made so he could use email on mobile.

I'd be surprised if the federal government hasn't created a mobile version of SIPRNet yet?

I work in politics (low level compared to these elected s). most of the committees use signal + email 2fa or similar now. But that does nothing against sate sponsored hackers with 0 days. Maybe rotating burner phones and chat platforms would work better, but probably not worth it for the vast majority unless doing something sketchy.
