There were lots of tears at the vice president’s residence Wednesday during the Joining Forces Veterans Day luncheon hosted by Michelle Obama and Jill Biden, who paid tribute to the troops and talked in detail about their sacrifices. Things got emotional again when Joe Biden thanked members of the military for their service, and talked about his late son, Beau, who was deployed to Iraq for a year in 2008 with the Delaware Army National Guard.

The vice president said he found out today that the Delaware National Guard’s headquarters in New Castle will be re-named the Major Joseph R. (Beau) Biden III Armed Forces Reserved Center. Beau, the former two-term attorney general, died of brain cancer in May at age 46.

“Our son did a lot,” Biden said, getting choked up. “But the proudest thing he ever did in his life was wear the uniform.”

While Beau was  in Iraq, the vice president said he would come into the kitchen in the morning to see his wife Jill standing there with her coffee and mouthing a prayer.

He told the service members and veterans in the room to remember how much their loved ones think about them while they’re overseas. “Every moment you’re deployed, you’re in their mind,” Biden said.

The luncheon, with a guest list of many military women, was in partnership with A&E and Lifetime, which aired a documentary this week called “Women of Honor.” The one-hour special featured the first lady and Jill Biden and showcased members of the military community, focusing on the stories of three women to represent veterans, spouses and caregivers.
