Arends appears to be a scam artist.

Veterans group hosting Republican candidate Donald Trump lost nonprofit status

The group’s chairman, Joel Arends of Sioux Falls, South Dakota, said the organization was appealing the IRS decision. He would not provide AP with copies of any tax returns, which would show how much money the group has collected over the years and how it spends its money. By law, such records are supposed to be available to the general public for inspection.
