Democratic state Sen. Loretta Weinberg, who is leading an investigation into the scheme to create traffic problems near the George Washington Bridge last fall, said Sunday that New Jersey Gov. Chris Christie should testify before her committee. “If Gov. Christie comes before our committee under oath and brings all these documents with him, I’d be more than satisfied,” she said on NBC’s "Meet the Press." She said the investigating committee that she co-chairs has not yet gotten all the evidence it needs, partly because some witnesses have invoked their privilege against self-incrimination. She said the committee is waiting for a court decision that will determine whether those witnesses will need to testify to her panel.The central issues are whether Christie ordered or had prior knowledge of the lane closings, and whether they were a form of political retribution directed at the mayor of Fort Lee for not endorsing Christie’s re-election bid.
