More reactions from Capitol Hillpublished at 04:52 Greenwich Mean Time
We have been seeing more reactions from both Republican and Democratic senators.
Republican Senator Marsha Blackburn criticised Biden's move, saying "there are two tiers of justice in Biden’s America", while Missouri Congressman Eric Burlison, also a Republican, said the pardon is "a brazen display of nepotism".
"This pardon will echo through history as a clear signal that under this administration, the scales of justice are tipped in favour of those with power, connections, and the last name Biden," he added.
On the other side of the aisle, Arizona Congressman and Democrat Greg Staunton disagreed with Biden's claim his son's prosecution was "politically motivated", saying he had been "convicted by a jury of his peers".
"I respect President Biden, but I think he got this one wrong," he wrote on X.
