Yeah, the MAGAts screamed bloody murder about the fact that HRC was using a non-government server to handle some of her official email traffic, even though it was not illegal to do so, at the time.
OTOH, they were strangely silent when Ivanka and Jarod (and probably TFG himself) were found to be using non-government email accounts to conduct official business, despite the fact that the law had been changed to make the practice illegal. IIRC, they didn't stop after it was made public.
Its also true that an investigation found that HRC never sent any classified material via that non-government server, although they did find (I believe) four classified items that someone else had sent to her.
