Washington (CNN) Several Supreme Court justices appeared sympathetic Tuesday to the arguments of former political aides convicted in relation to "Bridgegate" -- the George Washington Bridge traffic jam and political scandal that rocked the administration of then-New Jersey Gov. Chris Christie.

Bridget Anne Kelly, who served as an aide to Christie, was charged with using Port Authority resources to close several lanes leading to the George Washington Bridge, causing severe traffic issues as an act of political retribution. The scheme imposed crippling grid lock in Fort Lee, New Jersey, and came after Fort Lee's Democratic mayor had refused to endorse Christie's 2013 reelection bid.

Kelly and Bill Baroni, the deputy director of the Port Authority, were convicted for their roles and ultimately sentenced to 13 and 18 months of imprisonment, respectively. They are currently out on bond and they want the Supreme Court to reverse their convictions.

Referring to Baroni, Chief Justice John Roberts noted that he did have the authority "to regulate how lanes are used on the highway and say these are going to be used for Fort Lee, these aren't."

Justice Elena Kagan noted that while the two were convicted for property fraud the object of the scheme was not to obtain property, but to create a traffic jam and to "benefit people politically."
