SPRINGFIELD — MGM Resorts International Chief Executive Officer James Murren said Thursday the company has never wavered from its commitment to a world class project in Springfield and will make a full public presentation in mid-November to explain recent design changes that have triggered controversy.

Murren and other top executives of MGM met with Mayor Domenic J. Sarno Thursday in private, and then promised publicly to improve communications with city officials and the community after changes to the project and the recent closure of the MGM Springfield community office triggered surprise and criticism.

The commitment to the Springfield project “has never wavered,” Murren said, including its commitment to 2,000 casino jobs, 3,000 construction jobs and millions of dollars in annual revenues. The company will spend more than $800 million on the project, as stated from the beginning of the process, he said.
