Can I trouble you to elaborate on that? I've seen a very suspicious pattern resembling that at a charity I used to finance.
(A) The two "charities" conspire to collude.
(B) The 1st charity writes a hefty check (disguised as a "contribution") to the 2nd charity.
(C) The 2nd charity takes a cut, then launders the rest of it----depositing it into a bank account that is accessible only by the 1st charity's principles.
Sometimes the money is sent offshore---one infamnous case had an individual "contributing" to a US synagogue. The rabbi took a cut, then deposited the rest in an Israeli bank account for the contributor's use later.....all tax-free.
