Lawmakers are requesting a month of data, including text messages, sent or received by Regina Egea . She testified in July that she texted the governor her thoughts about December testimony on the bridge probe but later deleted the messages.

Christie said he does not remember receiving the messages.

It is not clear whether AT&T will turn over the records without a search warrant.

Committee co-chairman Assemblyman John Wisniewski tells The Record  the committee's lawyer advised it was an appropriate way to seek information.

The U.S. attorney's office has advised the committee not to call any more witnesses while it probes what happened.
