The U.S. Attorney's Office says Salgado was named in a 36-count indictment last week and surrendered at U.S. district court in Riverside Friday afternoon.
The indictment accused Salgado of conspiring to solicit and accept bribes from four vendors in exchange for acquiring new contracts or retaining existing contracts with the tribe.
Court papers show the vendors paid Salgado bribes in cash, payments to his creditors and checks payable to a company he established.
The indictment also alleges that those four vendors were involved in the tribe's real estate purchases, construction projects at the tribe's casino and reservation and also provided services at the casino.
The charges against Salgado include one count of conspiracy, 29 counts of bribery and six counts of filing false tax returns.
The U.S. attorney's office says the conspiracy charge carries a maximum penalty of five years in prison, while the bribery counts each carry a maximum sentence of 10 years and the tax charges carry three years maximum.
