President Joe Biden’s decision to pardon his son Hunter Biden drew sharp criticism from Republicans but also from fellow Democrats, who said the move sets a bad precedent and sows doubt in a U.S. justice system they have tried to defend against President-elect Donald Trump's attacks.

Biden, a Democrat whose term ends on Jan. 20, signed an unconditional pardon for Hunter, 54, on Sunday and said he believed his son had been selectively prosecuted and targeted unfairly by the president's political opponents. On Monday, the White House said Biden also feared his political opponents would continue to persecute the younger Biden in the future.

Biden previously pledged not to intervene in the two criminal convictions against his son. Many of his own allies said they sympathized with the president's urge to help out his troubled son but couldn't back the move.
