A GoFundMe campaign launched last month to pay for President Trump's border wall raised over $20 million from more than 300,000 donors. But that wasn't nearly enough.

Brian Kolfage, the campaign's founder, assured donors Friday that because the campaign didn't reach its $1 billion goal, they would be refunded. However, Kolfage announced he's still determined to build the wall on his own. Kolfage said in an update to the GoFundMe campaign page that he's formed a non-profit corporation named "We Build the Wall, Inc." That outfit will use donations to privately build "significant segments of the wall."

Donors to the GoFundMe campaign can either choose to accept their refund or request their donation be redirected to the newly established corporation.

"We are better equipped than our own government to use the donated funds to build an actual wall on the southern border,"Kolfage wrote.

To manage that task, Kolfage assembled an advisory board that includes retired Air Force Brigadier General Robert S. Spalding III, former politicians Tom Tancredo and Kris Kobach, Fox News contributor Sara Carter, and the controversial ex-sheriff David Alexander Clarke Jr.

Kolfage previously ran a Facebook page called Right Wing News that often circulated conspiracy theories. It was removed by the social media company last year.

Kolfage's announcement comes as federal workers protest the partial government shutdown, which has left 800,000 employees without pay. Trump has insisted the shutdown will continue as long as the federal budget excludes funding for his $5 billion wall.

In the meantime, Kolfage will be working to build his so-called "beautiful wall."
