Unanswered "Bridgegate" questions for Christie

4) What will Bridget Kelly say?

It seems only a matter of when, not if, Kelly is called to testify before the New Jersey legislative committee probing the bridge mess. It was her email to Wildstein – “time for some traffic problems in Fort Lee” – that took a he-said, she-said controversy about Christie’s staffers into the terrain of full-blown scandal.

An open question is whether someone told her to email Wildstein. If she considered herself free to do it on her own, that raises other questions about the climate in Christie’s office.

It’s a question that legislative investigators want answers to, and they seem certain to try to push for them through Kelly.
