ANNAPOLIS — Maryland lawmakers won’t return to Annapolis on Monday for a special session on gambling, according to a spokeswoman for Gov. Martin O’Malley.

The governor had set July 9 as the date he intended to bring the state legislature together to settle gambling issues that have divided the House and Senate this year. Lawmakers are considering an expansion of gambling that would authorize a sixth state casino, in Prince George’s County, and allow table games such as blackjack and roulette at all casinos.
