Harford County Executive David Craig wants a state work group discussing the expansion of gambling in Maryland to study Harford County as a potential casino site.

In a letter to commission Chairman John Morton III, Craig wrote that a Harford casino would generate tens of millions of dollars in new state revenues, and would help county officials pay for new spending obligations — including the shift of teacher pension costs from the state to the counties, a move that will cost Harford more than $10 million annually once the shift is complete in four years.
