An Air Force veteran who started a GoFundMe page to help fund construction of President Donald Trump’s border wall has already raised millions of dollars.

The crowdsourcing page launched this week by Brian Kolfage has a fundraising goal of $1 billion and had generated more than $6 million in donations as of Thursday morning.

In a statement posted on the page, Kolfage says the wall could be built if everyone who voted for Trump pledged $8 each.

Kolfage says he has contacted the Trump administration about where to send the funds.

A triple-amputee injured in the Iraq War in 2004, Kolfage went on to serve at Davis Monthan Air Force Base in Arizona.

Kolfage did not immediately return a voice message and email seeking comment.
