Since Hunter Biden's conviction on federal felony gun and tax charges over the summer, the White House has insisted that President Joe Biden had no intention of pardoning his son.
But on Sunday, the president issued a controversial sweeping pardon, saying his son had been subject to attacks from his political rivals.
Republicans have been quick to denounce the move - citing Biden's previous pledges not to intervene on Hunter’s behalf. The move has also cast a renewed spotlight on the role of presidential pardons and the independence of the US justice system.
President-elect Donald Trump called the intervention an “abuse”, while House Oversight Committee chair James Comer accused President Biden of seeking to “avoid accountability”.
