NBA Players Association is being investigated by the U.S. Attorney's Office in Manhattan, the union recently said in a statement. According to sources close to the situation speaking to Bloomberg under conditions of anonymity, union executive director Billy Hunter was served with a subpoena on Wednesday notifying him of the investigation.

Hunter has come under heavy fire recently stemming from allegations by union president Derek Fisher accusing Hunter of nepotism. A Yahoo! Sports investigation recently revealed that Fisher's claims may be well-founded. Hunter reportedly asked the NBPA to invest millions into a bank where his son, Todd, sat on the board of directors. The report also showed a history of hiring, and generously compensating, several family members for various jobs.

The NBPA has reportedly appointed a six-member committee to oversee an internal inquiry that will include a financial audit. In the statement, the union emphasized that "the NBPA will cooperate fully with the government's investigation."
