SALT LAKE CITY (AP) — The Utah Republican Party chairman says he doesn't know yet whether the party will abandon a costly lawsuit that's divided the GOP and saddled it with debt.

Chairman Rob Anderson wants the Republican Party to drop its legal battle over a law changing how political candidates are nominated but he doesn't know whether he'll move to end it without more support from party members.

The party's governing State Central Committee debated whether to drop the lawsuit during a six-hour meeting Saturday but adjourned without a vote.

A 2014 law passed by Utah's Republican Legislature and signed by GOP Gov. Gary Herbert allows candidates to bypass party nominating conventions and instead compete in a primary election by gathering voter signatures.

The Utah GOP has contended in a lawsuit that the law violated its constitutional rights.
