CINCINNATI (AP) — A federal judge has given preliminary approval to a $3.5 million settlement of a lawsuit against the IRS over alleged targeting of tea party and other groups.

U.S. District Judge Michael Barrett on Wednesday set a July 10 hearing in Cincinnati on making the settlement final, and set deadlines for claims and objections.

The Justice Department had announced last year that the case had been settled, pending approval of terms.

The lead plaintiff was the California-based Norcal Tea Party Patriots. The case swelled into a class-action suit by hundreds of groups. The court will decide how much each gets after legal costs.

The 2013 lawsuit during the Barack Obama administration was over treatment of conservative groups who said they were singled out for extra IRS scrutiny on tax-exempt status applications.
