PROVIDENCE, R.I. (AP) — The state's largest public-employees union has launched an effort to get out the vote for Providence Mayor Angel Taveras in the Democratic gubernatorial primary.

Rhode Island Council 94 and other unions have formed a coalition called "Working Families for Angel." Spokesman Jim Cenerini said Monday it will communicate with more than 16,000 member households in phone calls, mail and door-knocking.

Cenerini would not say how much the coalition is spending.

The presidents of Council 94 and the Rhode Island State Association of Firefighters said in a statement that Taveras is the only Democratic candidate who knows the "stresses working families are under."

Taveras faces General Treasurer Gina Raimondo and newcomer Clay Pell in the Sept. 9 primary.

Public-sector unions and retirees are suing over Raimondo's 2011 pension overhaul.
