President Joe Biden and his wife honored their late son, Beau Biden, on Thursday, just days before the president’s other son, Hunter Biden, is scheduled to stand for the first of his two criminal trials.

Thursday marked the ninth anniversary of Beau Biden’s death from brain cancer, believed to be linked to his exposure to toxic burn pits while deployed overseas. The president has frequently discussed his son’s death while lobbying for, and subsequently touting the passage of, the PACT Act, a veteran-focused healthcare bill.
