Its funny. A hostile IRS, the same one that audits Tea Party folk, gets to see his returns every year, for the last several decades.
Yep, if anything damaging were out there it would have already leaked, because Democrats can be trusted to be untrustworthy.
Plus, the IRS is literally up his butt 24/7 and he has teams of accountants to handle this stuff. The only thing the Dems are accomplishing here is to show the world that their priority is destroying opponents rather than doing anything positive.
