The lawyers for two former underlings of New Jersey Gov. Chris Christie say lawmakers should be able to offer their clients immunity from prosecution in exchange for providing information for their investigation of possible political payback.

The lawyers made their cases in court filings Friday on behalf of former aide Bridget Kelly and ex-campaign manager Bill Stepien.

The briefs are the latest court papers in a dispute over whether the legislative committee can force the two to provide documents and testify.

Christie fired Kelly and cut ties with Stepien in January after revelations that they were involved in last year's closure of lanes near the George Washington Bridge.

Federal prosecutors are also investigating the closures.
