This week, the Council on American-Islamic Relations (CAIR) released a report documenting over a billion dollars directed from philanthropy to anti-Muslim hate groups between 2014 and 2016, the most recent period for which publicly accessible data is available. The report is directed to mainstream philanthropy and provides a map for foundations to identify whether their funding directly or indirectly supports anti-Muslim advocacy groups. As NPR reports, CAIR is calling upon the sector for more accountability and oversight.
