yes, I'm sure you are in an uproar over this:
EPA Administrator Scott Pruitt and his aides have kept "secret" calendars and schedules to overtly hide controversial meetings or calls with industry representatives and others, according to a former EPA official who is expected to soon testify before Congress.

And, umm, sorry, there is little evidence of blatant corruption. And considering the things that are now ok for Trump and his admin to get away with, previous administration were angels. This campaign by Republicans is just a political ploy to keep their weasel Trump off the impeachment chair and possibly the jailhouse.
