“Mr. Kolfage deliberately and egregiously side-stepped his legal duty to pay taxes when he devised an elaborate scheme to hide income from his non-profit organization, We Build the Wall,” said IRS-CI Special Agent in Charge Brian Payne. “Kolfage repeatedly falsely claimed he would not take a salary and preyed on the generosity of hundreds of thousands of donors through his vast online fundraising scam. Today’s sentencing should serve as evidence that this type of blatant disregard for the rules and obligations that govern non-profit fundraising will not be tolerated.”
Kolfage’s federal prison sentence will be followed by 3 years supervised release, and he will also be required to pay restitution, to the United States of America, in the amount of $143,003 for his tax crimes, along with millions of dollars’ worth of forfeiture and restitution for his scheme to defraud We Build the Wall donors.
"Mr. Kolfage deliberately and intentionally preyed on the hearts and pocketbooks of hardworking Americans as a way to fund his own lavish lifestyle," said Sherri E. Onks, Special Agent in Charge of FBI Jacksonville. "The FBI and our law enforcement partners will not tolerate this type of blatant fraud against unwitting donors, and this sentencing should serve as a warning to those who attempt to take advantage of others.
