Mashantucket — Rodney Butler was re-elected chairman of the Mashantucket Pequot Tribe on Sunday in voting among tribal members.

Butler, chairman since 2010, was elected to a fifth consecutive three-year term on the tribal council, and later, in a separate vote, won a third straight term as council chairman.

Incumbent Jean Swift, the council treasurer, and Daniel Menihan Jr., a newcomer who had run unsuccessfully in previous elections, also were elected to the council. Crystal Whipple, the council vice chairwoman, failed to retain her seat.

Councilor Fatima Dames, who was not up for election to the council, was elected vice chairwoman, replacing Whipple.

The new terms commence in January.

The seven-member council governs the tribe and oversees the management of Foxwoods Resort Casino.

The Mashantuckets are partnering with their chief competitor, the Mohegan Tribe, owners of Mohegan Sun, to pursue a third Connecticut casino in the Hartford area.

That venture is aimed at MGM Springfield, the $800 million resort casino being built in Massachusetts, a few miles from Connecticut's northern border, and which threatens jobs and revenues at the tribe's existing casinos.

No details of Sunday's elections, which took place during the Mashantuckets' annual meeting, were provided.

According to a tribal source, Councilor Marjorie Colebut-Jackson, who was not up for election, was nominated for chairman along with Butler.

Whipple has served two terms on the council.

Swift joined the council in 2013, filling a vacancy that occurred when Steven Thomas, then the council treasurer, resigned before pleading guilty to a federal charge of embezzling from the tribe.

Nine tribal members, including the incumbents, presented themselves a month ago as candidates for the three council seats up for election. The field included Kenny Reels, a former council chairman, and Charlene Jones, a former councilor who has brought several lawsuits against the tribe.

In addition to Dames and Colebut-Jackson, the councilors whose seats were not up for election are Roy Colebut-Ingram and Richard E. Sebastian.
