President Joe Biden stamped out speculation Thursday that he could commute the sentence of his son, Hunter Biden, to help him avoid jail time and reiterated his vow that he will not pardon him.

The president’s comments mark his first on-camera remarks on the topic following Hunter Biden’s Tuesday conviction on felony gun charges, which he characterized as a fair trial. His immediate statement following the verdict confirmed his decision not to pardon his son, following promises made by White House officials that he would not do so.
