One major difference. trump would be hiding evidence of working to get a slummy hotel in Moscow....DURING the campaign. He'd be hiding evidence of Kushner trying to sell citizenship to Chinese for half a million bucks. He'd be hiding evidence of trump tower meetings between his campaign, and Russians. He'd be hiding evidence of the entirety of his staff being undisclosed foreign operatives.
And the cherry on top...he'd be hiding the $25k payment from trump charities to the Fla prosecutor's campaign, in exchange for not investigating trump university
What do you suppose Hillary was supposedly hiding?
