The U.S. Supreme Court has agreed to hear the appeal of Bridget Anne Kelly, the onetime aide to former New Jersey Gov. Chris Christie who was convicted for her role in the 2013 Bridgegate conspiracy.

The court on Friday granted Kelly’s petition for certiorari, which she filed earlier this year, contending that prosecutors in her case used, and courts below have accepted, “vague federal criminal law to impose ‘standards of … good government’ on ‘local and state officials.’”
