(Just to be clear: accepting a pardon is an admission of guilt.)
P.S. As loud a dog whistle as this pardon today is to Paul Manafort and any other potential witness in the Russia probe, it has long been my belief that anyone who relies on Trump keeping his promises (let alone expects him to act in a certain way based on what at best he seems to be maybe suggesting) is living in a fool's paradise. And that includes his children and son-in-law. If something is not in Trump's interest and most-especially if it could put him at risk, he will not do it.
