ST. PAUL — The Mille Lacs Band of Ojibwe is buying two big hotels in St. Paul.

Tribal leaders say the purchase is a new effort to diversify the band’s holdings beyond gaming revenue. The band won’t name the hotels until a Monday news conference. But, the Crowne Plaza Riverfront Hotel and the DoubleTree by Hilton have been up for sale by SP Hotels since last summer.

The tribe says Graves Hospitality Corp. will manage the hotels.
