Minnesota’s attorney general has accused Savers Thrift Stores of pocketing more than $1 million that should have gone to charities including the Lupus Foundation of Minnesota and Vietnam Veterans of America.

The legal office said that Savers, a privately held company based in the Seattle area, routinely misrepresented how much money it raised for nonprofit groups through clothing drives and other donations from customers. Savers would keep nearly all the money it raised from the sale of such items, the attorney general said in a report released on Monday.

The attorney general’s office is also holding the charities accountable for what it says is a failure to properly oversee how the stores raised money on behalf of the groups.

“My impression is, they sort of sign the contracts with this organization and then really largely turn a blind eye to the manner in which the contracts are being administered,” Lori Swanson, the Minnesota attorney general, said in an interview. “They have a responsibility to police the relationship.”
