Especially as the Prog demonstrators tend to violence.
what makes you think it's only progressives that want to see Trump's tax returns? Or for that matter what makes you think it's only progressives protesting? There a pro trump supporters out there too. Trump didn't win the popular vote and has been stuck being the least popular president at this point in his presidency in the history of the poll. Trying to insist it's just progressives that don't like Trump is just deluding yourself.
