Facing looming deadlines and with scores of legislation up in the air, Maryland delegates convened Saturday in Annapolis for a weekend bill-passing session.The 141-member House met for several hours to cram through a slew of bills before Monday’s “crossover day.” That’s the last day bills can pass either the House or the Senate and get a hearing in the opposite chamber without going through extra procedural steps. The General Assembly session is scheduled to end in just over three weeks.
