As U.S. President Donald Trump and Congress fight over a spending agreement to pay for a border wall, a man in Florida has taken matters into his own hands to fund the project.

Brian Kolfage, a Purple Heart recipient and triple amputee veteran, has set up a GoFundMe to pay for the wall. The campaign has gathered more than US$10 million as of late Thursday night.

“If the 63 million people who voted for Trump each pledge $80, we can build the wall,” Kolfage wrote on the crowdfunding page.

Kolfage says the campaign’s goal of $1 billion is the maximum amount GoFundMe allows. He says he has been in contact with the website to have the goal raised to the $5 billion budget Trump wants for the wall.

Kolfage says he is working with a law firm to ensure the money is used solely for the wall.

Trump is threatening to shut down the government if he doesn’t receive the money needed for the project.
