The only pardon that former President Joe Biden appeared to sign by hand was his son's, Hunter Biden, perhaps the most controversial of all of his acts of clemency.
During Biden's final weeks in the White House, he used the pardon power to hand out pardons and acts of clemency to over 1,500 people. During his final weeks, he also signed controversial preemptive pardons for other members of his family, as well as Anthony Fauci, Mark Milley, and members of the Congressional January 6 committee, but with the autopen.
According to Fox News, the one pardon that appears to have been hand-signed by Biden was for his son Hunter, who the president repeatedly said he would not pardon. Hunter Biden was found guilty of three felonies during an investigation into the president's son by special counsel David Weiss. The younger Biden was also charged with failing to pay over $1.4 million in taxes.
