Get this though. He has created a non profit to build the wall without the federal government.
Only raised 20m and he thinks a non profit will get er done. Hahahaahahaah

Refunds will be automatic. But not till April iirc.
He wants people to divert their donation to his non profit instead of getting that refund.
GoFundMe knew this would happen and is just happy to draw some interest payments from the 20m.
Non profits don't have imminent domain so their land costs will soar.
It just isn't going to happen.
