I would have pardoned him on the day that I was inaugurated, but I suppose that it is certainly better late than never. D’Souza was unfairly persecuted for daring to criticize Obama, and I am beyond thrilled that President Trump has reversed this injustice. D’Souza cannot get back the time that he served, but this is a very good second best. Now he can hold his head up high, because everyone knows that he did nothing to justify his treatment.
He made an astoundingly good book and movie out of the experience, Hillary's America: The Secret History of the Democratic Party however, so that is more than many political prisoners get. But the main thing that was killing him was not being able to vote.
It's ironic, since he was so all in for Cruz that he was nearly a NeverTrumper. But his books, movies and personal appearances make him one of the most valuable conservative communicators, and I'm so glad for him.
