The vote culminated a campaign by the tribes that begin shortly after MGM was awarded a license three years ago to build a casino in Springfield. The bill previously passed the Senate and now heads to Democratic Governor Dannel Malloy. The House of Representatives in Hartford, just before 2 a.m., voted 103-46 for a bill that allows the Mashantucket Pequot and Mohegan tribes to build a casino at the site of a former movie theater in East Windsor, just 13 miles from where MGM is building a $950 million casino in downtown Springfield. A bill to allow construction of a third tribal casino in Connecticut cleared the legislature early this morning meaning the yet-to-open MGM Springfield casino could face a competitor just a few miles away down Interstate 91.
