I'm sure during the course of the campaign, Trump will be pressed on the question of why he had Shrillary at his wedding and we can choose to accept or not accept any reason he gives us. In the meantime, we are only speculating and jumping to conclusions.
If YOU want to be intellectually honest about it, as long as Trump wanted to stay a private citizen, it made no difference who he invited to his wedding. Once he decided he wanted to run for president, ALL of his past associations became fair game for review.
If I ever ran for public office, how could I ever satisfactorily explain that one away to my critics other than to say I could not foresee future events?
Did you know he was a child molester when you invited him? If not, then that is a false equivalency. Trump invited the Clinton's to his wedding in 2005. Are you saying Trump had no idea what the Clintons stood for and represented after 8 years of Bubba as president and 5 years of Hillary as Senator?
