Meh -- "it's just a GD piece of paper"
Nothing New Under the Aten!
Regarding Trump, he has a perfect alibi here: when he found out about what Manafort had done, HE FIRED HIM. In Aug 2016. Funny how that was the same time that Podesta’s filed new forms.
Manafort played loose with the tax filings so I have no sympathy for him.
As far as having a search warrant and picking up other stuff than noted in the warrant, I think the concept of plain sight comes into play here as they were there legally.
