A supporter of President Trump’s border wall proposal has started a GoFundMe to help pay for the project — and the fund skyrocketed to more than $2 million Wednesday night after being live for just three days.

Brian Kolfage, a Trump voter and disabled Iraq War veteran with no connection to the administration, wrote that he set up the page because “President Trump’s main campaign promise was to BUILD THE WALL. And as he’s followed through on just about every promise so far, this wall project needs to be completed still.”

Trump campaigned on building a “great wall” on the southern border during the 2016 presidential election.

As the end of Trump’s second year in office comes to a close, his administration has not built the wall or secured funds for it — and a budget proposal passed Wednesday by the Senate did not fulfill Trump’s call to provide funds for it.

Kolfage wrote on his fundraising page that if every Trump voter donates $80 to his wall-building campaign, they will raise the $5 billion that Trump says is needed to build the border wall.

“Even if we get half, that’s half the wall. We can do this,” Kolfage wrote on the GoFundMe page.

As of Wednesday night, the campaign had raised nearly $2 million, with large and small donations pouring in nearly every minute.

Kolfage assured donors that he has contacted the Trump administration and every penny of their donations would go to funding the “Trump wall.”

“We have many very high level contacts already helping,” he wrote.
