Up Close: George Washington Bridge scandal

There's now hard evidence that people close to New Jersey Gov. Chris Christie conspired to intentionally clog traffic on the world's busiest bridge, the George Washington.

David Wildstein admitted, under oath, that it was a political vendetta that he ordered lane closures on the bridge and engineered four days of gridlock in Fort Lee to punish Mark Sokolich, the mayor of Fort Lee, for his refusal to endorse Christie's re-election.

The scheme created havoc for Sokolich's constituents and violated various criminal laws.

U. S. Attorney Paul Fishman announced the indictments Friday of Christie's former Deputy Chief of Staff Bridget Anne Kelly, and former Port Authority Deputy Director William Baroni. Wildstein pleaded guilty Friday and implicated both, admitting he conspired with Kelly and Baroni to punish Sokolich.

He admitted that they provided no advance notice to the mayor, chief of police or residents.

Christie has insisted that he had no knowledge of the scheme, and prosecutors seemed to indicate there is no evidence so far that he did.
