A former aide to Gov. Chris Christie whose job included getting re-election endorsements from mayors said Tuesday that he was "dumbfounded and disappointed" to learn that a northern New Jersey mayor was apparently targeted in a political payback plot orchestrated by Christie loyalists.

Following Tuesday's near-five-hour hearing, we still don't know who ordered the unannounced access lane closures to the George Washington Bridge in September, or why the directive was given.

Gov. Chris Christie and other defendants will get more time to file their responses to two lawsuits related to the September lane closures at the George Washington Bridge that are central to a traffic jam scandal threatening the Republican governor's political ambitions.

The attorney leading the Christie administration's internal investigation into Bridgegate has formally released a report claiming Gov. Chris Christie did nothing wrong. However, the Democratic co-chairs of the Select Committee on Investigation, the legislative panel probing the scandal, are not at all convinced.

An internal Bridgegate report places the blame for the controversial lane closings at the George Washington Bridge and an ensuing coverup entirely on former Port Authority official David Wildstein and former Christie aide Bridget Kelly.

The Bridgegate scandal continues to dog New Jersey Gov. Chris Christie, with political pundits and statehouse insiders believing the unannounced access lane closures to the George Washington Bridge in Fort Lee dashed his prospects as a 2016 presidential candidate. But Christie Wednesday night said he is not thinking about 2016, either way.

Bonnie Watson Coleman has stepped down from the legislative committee investigating Bridgegate after a TV appearance in which she called for Gov. Chris Christie to resign over the scandal.

Newly released versions of digital communications between two key Bridgegate figures portray arrogance, pettiness and callousness but shed no new light on the possible involvement of others.

More than a dozen new subpoenas will be issued as part of the ongoing Bridgegate investigation, a joint legislative committee announced following a hearing in Trenton on Monday.
