President Joe Biden celebrated a quiet Christmas with his family at the White House and spoke with service members stationed around the world.

"They're away from their families to protect us," Biden said in a tweet. "And they have the thanks of a grateful, indebted president."

The White House said Biden and the first lady, Jill, called members of the Army stationed at Panama City, Panama; the Navy aboard the USS The Sullivans in the Arabian Sea; the Marine Corps at Marine Corps Recruit Depot San Diego; the Air Force at Okinawa, Japan; the Space Force in Europe; and the Coast Guard aboard the cutter Bertholf in Alameda, California.

This is Biden's second Christmas as president. On Saturday, Biden and his family joined a Mass on Christmas Eve at the White House and continued their holiday tradition of an Italian dinner.

The president and first lady on Friday also carried on another tradition with their second holiday visit to Children's National Hospital. Biden was the first sitting president to join his wife when they visited hospitalized children and their families before Christmas last year, according to the White House.

Surrounded by Christmas trees and holiday decorations, the first lady read "The Snowy Day" with the president's help holding up the book.

Biden last week encouraged national unity in a recorded address, calling out the nation's political divisions and saying he hoped "this holiday season will drain the poison that has infected our politics and set us against one another."

"So, this Christmas, let's spread a little kindness," he said.

'Tis the season of giving back, and Gary Sinise is doing just that.The actor held his annual Snowball Express for children of fallen military service members. Typically his event is held in person at Walt Disney World, but because of the COVID-19 pandemic the actor went virtual for the second year.Along with Sinise, Tom Hanks, Tim Allen, Steve Buscemi, Matthew McConaughey, Gordon Ramsay, Kristen Bell, Simone Biles, Caeleb Dressel and Jordan Chiles were among those who took part with messages. Idina Menzel even sang "Show Yourself' from "Frozen II."The kids were treated to a full day of virtual experiences from magic by Penn & Teller, Bindi and Robert Irwin from their animal sanctuary in Australia, yo-yo lessons from two-time world champion Gentry Stein, animation and even cooking lessons.For over a decade, Sinise has given back to veterans through his Gary Sinise Foundation.

Heartwrenching details began emerging Friday about some of the 13 U.S. troops killed in a horrific suicide bombing at Afghanistan's Kabul airport, which also claimed the lives of more than 100 Afghans.

Eleven Marines, one Navy sailor and one Army soldier were among the dead, while 18 other U.S. service members were wounded in Thursday's bombing, which was blamed on Afghanistan's offshoot of the Islamic State group. The U.S. said it was the most lethal day for American forces in Afghanistan since 2011. The White House said President Joe Biden will look for opportunities to honor the service members who lost their lives, many of whom were men in their early 20s.

Here are details about some of the victims:

Rylee McCollum, 20

Rylee McCollum, a Marine and native of Bondurant, Wyoming, was married and his wife is expecting a baby in three weeks, his sister, Cheyenne McCollum, said.

"He was so excited to be a dad, and he was going to be a great dad," McColllum said. She said her brother "was a Marine before he knew he was allowed to be a Marine ... He'd carry around his toy rifle and wear his sister's pink princess snow boots and he'd either be hunting or he was a Marine. Sometimes it would be with nothing on underneath, just a T-shirt."

McColllum said her brother wanted to be a history teacher and a wrestling coach once he completed his service. Another sister, Roice McColllum, told the Casper Star Tribune that her brother was on his first deployment when the evacuation in Afghanistan began.

"We want to make sure that people know that these are the kids that are sacrificing themselves, and he's got a family who loves him and a wife who loves him and a baby that he'll never get to meet," Cheyenne McCollum said.

Regi Stone, the father of one of Rylee McCollum's friends, described McCollum as "a good kid," who was resilient, smart and courageous. Stone shared a note that his wife, Kim, sent to their son Eli Stone, who is also in the military and deployed elsewhere. In the note, Kim wrote that she remembered telling the friends to run the other way if they had to go in first and that both of them said, "If we die doing this, we die doing what we love."

Jared Schmitz, 20

Marine Lance Corporal Jared Schmitz grew up in the St. Louis area and was among a group of Marines sent back to Afghanistan to assist with evacuation efforts, his father, Mark Schmitz, told KMOX Radio.

Mark Schmitz said his son always wanted to be a Marine. He said he learned of his son's death when the Marines came to his home in Wentzville, Missouri, at 2:40 a.m. Friday.

"This was something he always wanted to do, and I never seen a young man train as hard as he did to be the best soldier he could be," Schmitz said of his son. "His life meant so much more. I'm so incredibly devastated that I won't be able to see the man that he was very quickly growing into becoming."

Taylor Hoover, 31

Staff Sgt. Taylor Hoover, of Utah, had been in the Marines for 11 years and was remembered as a hero who died serving others, his father Darin Hoover said.

Darin Hoover found out his son had died in the blast on Thursday night when Marine staff sergeants who came to his house in a suburb of Salt Lake City.

"He is a hero. He gave his life protecting those that can't protect themselves, doing what he loved serving his country," Darin Hoover said.

He said he heard from Marines throughout the day Friday who served with his son who said they are grateful they had him as their sergeant.

"They look back on him and say that they've learned so much from him," Darin Hoover said. "One heck of a leader."

His father said his son was also a best friend to his two sisters and loved all his extended family. He had a girlfriend in California.

A high school football player who graduated from Hillcrest High School in Midvale, Utah, in 2008, Taylor Hoover was the kind of guy who "lit up a room" when he came in.

"He was the most-loving, giving, understanding person you could ever meet," Darin Hoover said.

Utah Gov. Spencer Cox was among officials who offered their sympathies to Hoover's family. He said flags will be flown at half-staff at all state facilities and public grounds until Aug. 30 to honor all those killed in Afghanistan. "We honor his tremendous bravery and commitment to his country, even as we condemn the senseless violence that resulted in his death," Cox said.

Deagan William-Tyeler Page, 23

Corporal Daegan William-Tyeler Page served in the 2nd Battalion, 1st Marine Regiment based at Camp Pendleton, California, and planned to go to trade school and possibly become a lineman after his enlistment ended, his family said in a statement.

He is mourned by his girlfriend, parents, stepmom and stepdad, four siblings and grandparents, the family said in a statement released by a family friend. The statement said the family did not wish to speak to the media at this time.

"Daegan will always be remembered for his tough outer shell and giant heart," the statement said. "Our hearts are broken, but we are thankful for the friends and family who are surrounding us during this time. Our thoughts and prayers are also with the other Marine and Navy families whose loved ones died alongside Daegan."

U.S. Rep. Don Bacon, a Republican from Nebraska, said in a statement that he was heartbroken to learn of Page's death. "Corporal Page is an American hero who gave the last full measure of devotion. He served his country honorably, and his service will never be in vain."

Stepmother Linnae Knauss said Ryan planned to move to Washington, D.C., after he returned to the U.S.

"He was a super-smart hilarious young man," she said.

The congressman's press secretary, Dana Youngentob, said Pentagon representatives visited Cuellar's Washington office to inform him of Espinoza's death. Cuellar's office also received an official death notice from the Pentagon.

In a statement, Cuellar said Espinoza "embodied the values of America: grit, dedication, service, and valor. When he joined the military after high school, he did so with the intention of protecting our nation and demonstrating his selfless acts of service."

Cuellar concluded, "The brave never die. Mr. Espinoza is a hero."
