I think Trump's ratings comment about the pardon during the hurricane actually make it seem worse than if it had just been to hide bad news. What a bad person.
My guess is his comment is just his off the cuff auto "no puppet" reflex where he has to say he did the opposite of whatever negative thing he is accused of in the moment i.e.
Media: Trump timed pardon to bury it under other news
Trump: Uh uh, I timed the pardon to get the MOST coverage for it!
Would have been so easy for him to say it was just coincidence, and that the pardon came right after he made a final decision while visiting Arizona. But his ego won't let it go quietly.
