This past Memorial Day, many veterans spent the day, in observance of those who fell in battles either long past or very recently.

But, along a stretch of the US/Mexico border one veteran on a mission, broke ground on a project, building the first crowdfunded section of border wall in America.

The groundbreaking marks a major milestone for Kolfage, a triple amputee veteran who first began the We Build The Wall GoFundMe campaign in December. The campaign—launched during the heat of the congressional fight over border wall funding—has since raised over $22 million from online donations, many of them small-dollar contributions. The campaign’s goal is to raise $1 billion.

On the groups GoFundMe page, Brian Kolfage describes himself as “As a veteran who has given so much, 3 limbs, I feel deeply invested to this nation to ensure future generations have everything we have today.”

The wall is similar to the design used by U.S. Border Patrol, but the organizers claim their wall can be built faster and cheaper. The project was led by construction mogul Tommy Fisher, CEO of Fisher Industries.

“This is the first time any private organization has built a portion of the wall on private land. It’s happening right here in the El Paso area, and it’s not just any piece of land,” Kris Kobach, an informal immigration adviser to the White House and general counsel to We Build The Wall, said on Monday, May 27, on Fox News

The initial section of the wall is 1 mile long and came in at an estimated cost of between $6 million and $8 million. The group plans to sell the wall to the U.S. government for one dollar and release the title to it.

With the first section of the project underway, and now public, Kolfage and those involved were able to fend off accusations and questions about delays and the reason for keeping many details out of the public spotlight. Kolfage had long maintained organizers had to keep details of the project quiet to protect the safety of the landowners involved.

The founder of the group pushed back against the “haters” in a Monday Twitter post, “All the haters said it was impossible!! Bahaha where ya at now?”
