Yep, so far he has suggested that Priebus is responsible for the felonious leaking of Mooch's financial disclosure statement when he was at the Import-Export Bank. The fact that I-E Bank disclosures are public record, and can be obtained online by anybody, apparently don't bother Mooch at all. In Moochworld, which appears to be a suburb of Trumpworld, "leaking" something that is publicly available is a felony.
It's all about appearances; there will probably be lots of people on here who believe that it was all 'leaked' somehow, too.
