Sorry, but Presidents of the United States have the written authority to pardon prisoners, whoever they may be. Roger Stone was his adviser. The Democrats began beating up on innocent staffers who served in the Executive Branch under President Trump. He likely prevented a human tragedy when he pardoned innocent people who were demonized by his enemies, so they could make President Trump look bad when he was so successful at making America great again.
Here is one of the uglier TDS creepsisters demanding her minions double down on stalking and humiliating the Trump Executive Branch employees:
That is Unconstitutional, and Maxine Waters lost half of her worshipers who knew stalking is also against the law.
likewise, the governor has that same pardon power, limited, of course, to state crimes.
