Government officials are held to account during an election.
Can you imagine what would happen to this forum if every time someone posted their opinion they had to provide three corroborating links to science reports to prove their point? The moderators would be napping all the time.
If the PEER group has an issue with what the EPA does, let them sue the EPA and show the harm that was done to them by their new or revised ruling. That's how things are settled in court. Russ is right that this will be thrown out on appeal. You can't force people to provide evidence to what's going on in someone's mind because they gave an opinion.
Pruitt was appointed, not elected.
What do the posting standards of an online forum have to do with what's expected of someone in high office when speaking in public? Would it be ok, do you think, if Pruitt's opinion was that coal miners did NOT contract black lung disease in the mines? Would it be ok, for someone in high office, who is supposed to be making decisions for the protection of citizens came out against blood transfusions or the use of latex by surgeons? Do you really think it's ok for someone in high office with those "opinions" to voice them?
The most astounding thing about Pruitt is that he still has his job, considering all the other controversies he has been involved in. But maybe this is how Trump is going about clearing out the swamp, by putting such clowns in charge (or leaving positions open) that those offices become, in effect, completely useless.
You may be correct about the specifics of this specific court case. I don't understand the details of the law suit to begin with, seems nuts to me at first glance, but lots of things that happen in courts mystify me.
