FORT LAUDERDALE, Fla. (AP) — Leaders of the Seminole Tribe of Florida — the first U.S. tribe to offer high-stakes gambling — have spent millions of dollars from the group's vast casino income on themselves and their relatives, according to a report.

The spending has triggered audits by federal regulators and complaints among Seminoles that the gambling profits benefit certain members at the expense of the rest of the tribe, the South Florida Sun-Sentinel reported Sunday after a review of thousands of pages of tribal documents including audits, budgets and Tribal Council resolutions.

Phil Hogen, chairman of the National Indian Gaming Commission, which regulates tribal spending of gambling profits, told the Sun-Sentinel that the spending practices "cry out for some inquiry, and they will receive that."

Each of the tribe's almost 3,400 members receives about $120,000 annually in profits from Seminole enterprises, mostly casinos. However, since 2000, Tribal Council members have spent more than $280 million from discretionary funds they control on travel, lavish homes, luxury vehicles, boxing rings, basketball courts and even cosmetic surgery, the newspaper said.
