>> reporter: correspondent, michael isikoff , spoke to kelly , and her lawyer, michael critchley. she would not answer questions.
>> she has rights that need to be asserted.
>> reporter: her fifth amendment right against self incrimination. the 42-year-old single mother of four was fired by governor christie in january after e-mails showed she played a role in ordering the deliberate snarling of bridge traffic. today, with this 47-page brief, kelly will argue in court that she cannot be forced to turn over personal e-mails, calendars and documents, because that information would, in effect, provide testimony that could be used against her.
>> the mere act of requiring her to produce documents has a testimonial aspect. and that is something that the fifth amendment protects against.
>> reporter: and not only kelly , but governor christie's former campaign manager, bill stepien, also has a date in court and can make that same argument. he too is trying to not have to turn over any personal e-mails and documents. natalie?
>> big day there again in court. kelly o'donnell in trenton, new jersey. it thank you.
