President Biden on Wednesday night released a statement marking the second anniversary of his heavily criticized Afghanistan withdrawal.

Biden's statement touted the operation as one of the "largest airlifts in history," but he made no specific reference to the 13 U.S. service members who died defending the Kabul airport during the operation. He did mention them during a separate event on Saturday, however.

"Today, we pause to remember the selfless service of generations of brave women and men over the course of the conflict — who, time and time again, sacrificed their own safety and security for that of their fellow Americans. That includes the 2,461 U.S. service members who made the ultimate sacrifice, and 20,744 of their brother-and-sisters-in-arms who were wounded in action," Biden wrote.

"I remain forever grateful to the military members, diplomats, intelligence professionals, and development specialists who not only worked together to advance the United States’ Afghan mission for two decades — but who also conducted our withdrawal with the same resolve and bravery that defined U.S. service in Afghanistan. Together, they helped evacuate approximately 120,000 people in one of the largest airlifts in history. And every day since, they have skillfully used every military, diplomatic, and intelligence resource available to continue to protect our homeland from terrorist threats in Afghanistan and around the world," he continued.
