I believe that was all from work we had done together in early 2015 with SCL during the midterms. The billing and administration item that they were referring to was that they had given money to us to place ads. We were not able to get through all of the budget that they had assigned for that period. We simply directed Facebook to refund the money directly to them, as opposed to us and back.
