A legislative source reports two top aides to Mayor Bloomberg – Deputy Mayor Howard Wolfson and Director of Legislative Affairs Micah Lasher – are huddling with Assembly Speaker Sheldon Silver in hopes of landing a charter school deal before the day is out.

The DN’s Glenn Blain reported earlier today that rank-and-file Democrats had been told to prepare themselves for a long night at the Capitol, with session being pushed back from 3 p.m. to 5 p.m.

Now session has been rescheduled yet again, according to my source. It’s currently set for 7 p.m., but there’s a possibility things won’t get underway until 9 p.m.

Meanwhile, the Senate has called it quits for the day and is planning to return at 9 a.m. tomorrow to vote on a deal to keep the parks open and – for now, anyway – a charter school bill.
