PROVIDENCE, R.I. (AP) — Attorneys for the state and its public unions have reached a proposed settlement to end the legal challenge to Rhode Island's landmark pension overhaul — but the public will have to wait for the details.

Gov. Lincoln Chafee and Treasurer Gina Raimondo gave a closed-door briefing to top lawmakers Monday. While Chafee declined to comment, House Speaker Gordon Fox says the briefing concerned the "highlights" of the proposed settlement.

The case has been in closed-door mediation for more than a year after public-sector unions sued to stop the 2011 pension overhaul, designed to save the state billions by raising retirement ages and suspending pension increases.

Lawmakers must sign off on any settlement.

Lawyers in the case have scheduled a joint press conference to update the public on Wednesday.
