Good question for a curious investigative reporter!
Call this out there, but my gut tells me the whole thing was cooked up by Hillary, her operatives, Obama's operatives and the DNC. The law group laundered the money and the Steele and Brit connection were 'drafted' to provide cover, "he did it, it's his idea, he didn't like Trump, they sold it to us, blah, blah." Remember, through the years, Hillary always has plausible deniability.
True.
