The crowdfunding page has been shared on Facebook over 760,000 times, and has been receiving regular donations by the minute.
Kolfage states on the page that it's "up to Americans to help out and pitch in to get this project rolling".
In a recent interview with conservative commentator Derek Hunter, Coulter went so far as to say she wouldn't vote for Trump in 2020 if he didn't build the wall. The spending measure now goes to the House of Representatives, and it has to be signed by Mr. Trump.
Senate Minority leader Chuck Schumer of NY said Democrats oppose Trump's border demands because the wall is "inefficient" and because Trump, as a candidate, promised that Mexico would pay for it, which Mexico has refused to do.
"That equates to roughly five billion dollars, even if we get half, that's half the wall".
The crowdfunding page is now receiving donations in the names of former Secretary of State and presidential candidate Hillary Clinton, former President Barack Obama, and more.
They include: Mark Meadows of North Carolina, Jim Jordan of Ohio, Paul Gosar of Arizona, Steve Pearce of New Mexico, Jody Hice of Georgia, Ralph Norman of South Carolina, Andy Biggs of Arizona and Morgan Griffith of Virginia. More than 11,400 supporters have donated.
The president's push for funding for a border wall was bring tied into government budget funding and would cause a partial government shutdown by midnight on Friday.
Trump initially told congressional leaders that he would accept nothing less than $5 billion for his wall in a bill to keep most of the federal government open.
Those comments appeared to be a bit too much for the president, who seemed to unfollow Coulter on Twitter as a result.
