A Florida Air Force veteran has raised nearly $1million to build President Donald Trump's promised border wall.

Triple amputee Brian Kolfage, 37, created the GoFundMe account on Sunday titled We The People Will Fund The Wall, and in three days has already raised over $900,000 of its $1billion goal.

'It's up to Americans to help out and pitch in to get this project rolling,' the page reads. 'If the 63 million people who voted for Trump each pledge $80, we can build the wall.'

Trump is demanding $5billion to build the southern border wall with Mexico, and is threatening to shut down the government if he can't get the funding.

The fundraising page says it has contacted the Trump Administration to secure a point of contact where all the funds will go, but adds it has 'many very high level contacts already helping'.

'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 page says, elaborating on Kolfage's history as a Purple Heart Medal recipient.

'Too many Americans have been murdered by illegal aliens and too many illegals are taking advantage of the United States taxpayers with no means of ever contributing to our society,' it continues.

Kolfage says his grandparents immigrated to the US legally, adding, 'they did it the correct way and it's time we uphold our laws and get this wall BUILT!'

Meanwhile, President Trump on Wednesday claimed the military would build his border wall and Mexico would pay for it - indirectly under the new trade agreement.

Trump said Wednesday the new trade deal means Mexico will pay for his wall

'Mexico is paying (indirectly) for the Wall through the new USMCA, the replacement for NAFTA! Far more money coming to the U.S. Because of the tremendous dangers at the Border, including large scale criminal and drug inflow, the United States Military will build the Wall!,' he tweeted.

His declaration comes after the White House ditched its demand for $5 billion in funding for the border wall amid negotiations to keep the government open.

Trump also vowed on Wednesday he 'will win on the wall' after the White House signaled it was ditching its demand for $5 billion in funding for his signature issue.

'One way or the other, we will win on the Wall!,' Trump tweeted on Wednesday morning as the clock ticked toward Friday's partial government shutdown.

White House Press Secretary Sarah Sanders said Tuesday the administration's legal team was looking into whether the White House could redirect funds to build the border wall.
