North Carolina’s only federally recognized American Indian tribe could soon offer sports and horse wagering to patrons at its two casinos. The General Assembly gave final approval Monday night to a measure that would give the Eastern Band of Cherokee Indians the authority to offer the additional betting. The House voted for the measure that had already cleared the Senate three months ago. The bill now goes to Gov. Roy Cooper’s desk. A Cooper spokesman says the bill will be reviewed before he makes a decision on whether to sign it. The sports-book option took shape after the U.S. Supreme Court struck down a federal law last year that made most sports gambling illegal. State law already lets the Eastern Band offer live poker, slot machines and video-style games.
