David Samson, the former chairman of the Port Authority of New York and New Jersey, will plead guilty to a felony charge not directly related to the so-called "Bridgegate" scandal in which he was involved. Samson, an appointee of New Jersey Gov. Chris Christie, allegedly curried favor with United Airlines to set up a route to his vacation home in South Carolina—one that was scrapped just a few days after Samson resigned from his post in March 2014. The guilty plea could come as early as this week.
