Well, today marked a national day of mourning for former President Jimmy Carter, who died last week at the age of 100.

Carter state funeral was held this morning at the National Cathedral in Washington, where he was eulogized by President Joe Biden, family members and close friends, all giving personal memories and reflections on Carter's legacy as leader of the free world and his extensive work after every living former president attended the ceremony.

Carter's casket was then flown to his hometown of Plains, Georgia for a second funeral at the Baptist Church, where he taught Sunday school.

Carter is being buried at his home alongside former First Lady Rosalynn Carter.

President Carter left memories around the world, including in Union Beach, where he and Rosalyn joined a habitat for humanity effort to help rebuild the Jersey shore in the aftermath of Sandy.

Work that was also remembered today.

Ted Goldberg reports.

What an experience.

My goodness.

It's been more than 11 years since Jimmy Carter helped Union Beach rebuild after Superstorm Sandy.

Memories of that day are still fresh for volunteers who worked with him.

It was amazing.

Amazing, amazing.

What a lovely, lovely man.

And Rosalynn Oh my goodness.

Her priority was that if children had a home to live in, a safe home, they would excel in education.

And that was her priority at the time.

President Carter was a wonderful man.

He was really a humanitarian and he helped a lot of people.

James and Nancy Duran were among the 200 or so volunteers who joined President Carter in rebuilding this home, one of many destroyed in Union Beach.

Carter just turned 89.

So some volunteers were curious how hard he would work.

He walks around with a hammer and a scarf and he talks to people but doesn't do any work.

After Sandy, habitat for humanity helped more than 120 families in Monmouth County with either building homes or doing critical repairs.

A lot of that work was done in Union Beach.

The town was shut down because they were afraid of looters.

It was it was devastating.

It was just unbelievable what happened to the people who lived there, with the flooding and the wind damage and everything else that happened to their houses.

And you just felt sorry for them.

You had to do something to help them.

And now to come here and help you is just a part of our life.

And we are really grateful that you let us come and join you.

After following security protocols, Secret Service came down.

We had to go through all these things.

The former president went to work with his hammer and scarf.

We're at Union Beach and he showed up with the wife, Rosalynn.

I couldn't believe how anxious he was to start working.

He worked a solid three hours without any help.

You know, I was shocked.

Rosalynn was a little frail, but she stayed at the work site with him.

But boy, could he swing a hammer.

I said to my husband, he goes, oh no, he swings that big, heavy hammer.

There was a real sense of community, a real sense of, you know, getting people back into their homes as quickly as possible.

Elmer Lamberson Jr. Who lives in the house that Carter helped to build said, quote, President Carter's work with habitat has given so many families like ours a fresh start and a place to call home.

His dedication and compassion helped to restore hope and dignity to my father.

After the devastation of Sandy, we always say that Habitat's number one volunteer is President Carter, and he most certainly contributed to, I think, the response of the volunteer community.

Carter was president for four years and spent much longer than that as an ambassador for habitat for humanity, to reach across that divide and touch the hearts and lives and future and self-respect and hope and dreams of people that have never had a decent house.

And habitat is the best way I know to cross that divide easily, because you meet families that are in need on an equal basis.

Swinging a hammer or making boxes or whatever it does during the day, and you learn to respect them as equals to you.

His legacy as a humanitarian may be more than a president is still felt by many here.

He was such a humble man, and it was just so interesting to work with a man who was formerly the president of the United States.

He spoke to our volunteers, and the first thing he said to them, well, I'm going to go because I got to get back for Sunday school.

I teach Sunday school at Maranatha Baptist Church in Georgia.

I was like, this man's a president, and he's doing all these wonderful things and caring about people in Fairhaven.

I'm Ted Goldberg.

Thank you and God bless you all.
