Update 1:15 p.m. A D.C. Public Schools spokeswoman declined to confirm that school closings would be announced by the end of 2012, as the D.C. Council’s budget office told the National Conference of State Legislatures. “I didn’t tell them that, and I don’t know where the D.C. Council budget office gets their information,” Melissa Salmanowitz said. She was not able to say if it would take longer than this winter for the closings to be announced. “We haven’t issued a specific timeline yet,” she said. Officials in the budget office were at a conference in Chicago and unavailable.
