A triple-amputee Air Force veteran who raised more than $20 million toward building a wall on the U.S./Mexico border is trying to circumvent efforts by the fundraising site GoFundMe to return the donations to more than 325,000 donors.

Brian Kolfage, who was severely wounded while serving in the Iraq, began accepting donations in December, but on Jan. 11 he announced that he would use the money raised to create an organization that would build the wall itself rather than giving it to the government.
