The White House said on Monday that President Joe Biden pardoned his son Hunter in part because of concern his political opponents would continue to persecute the younger Biden in the future, as a growing chorus of Democrats and Republicans criticized his decision.

The pardon comes after Biden repeatedly said he would not use his executive authority to pardon his son or commute his son’s sentence. And in his statement, Biden said he was granting the pardon because his son had been “selectively, and unfairly, prosecuted.”

Hunter Biden pleaded guilty to nine tax violations in September and was convicted in a separate case on felony firearms-related charges. He could have faced decades in prison, though his upcoming sentencing was likely to be a much less severe punishment.
