>Trump and Cruz are the ones now saying that 'Hillary started it'
That is probably true - however, I'm sure it wouldn't surprise you to know that politicians will "pimp out" political hit jobs on candidates that don't trace back to the leader. I'm sure that people like Cllinton and Trump have a form of "omerta".
And in fairness, even though I'm not a fan of Trump and Cruz, people on the left often blame them for actions of their followers. Can't have it both ways.
