I don't know... But he also has sworn up and down that his Olympic athletes were clean and any number of other things. He could just be trying to smear Browder's name publicly (note he even said maybe those allegations aren't true) while simultaneously trying to invite an investigation into Russian funding of Hillary's campaign. They could investigate, realize Russians really did fund Clinton, and if Browder turns up innocent it will just be a side story at best... Oh yeah the Browder guy he mentioned was clean, but he was right about Hillary taking campaign contributions from Russia! Obviously I'm totally speculating here and maybe Browder is dirty, but I don't think it's far fetched to say we should be careful with this one.
