Former U.S. Solicitor General Theodore Olson will join the state of Rhode Island’s legal team in a case over American Indian tribal land that has reached the U.S. Supreme Court.

A spokesman for Gov. Don Carcieri said Olson, a prominent appellate lawyer, will be paid a flat fee of $200,000 from the governor’s contingency account. Carcieri has discretion on how money from that account is spent.
