LONDONDERRY — Gov. Chris Sununu’s bid for re-election has received the endorsement of the Professional Fire Fighters of New Hampshire, which represents about 2,000 active and retired public-safety officers, according to a news release from his campaign.

“Chris Sununu has our backs in Concord, and we have his back this election,” Bill McQuillen, president of the Professional Fire Fighters of New Hampshire, said in the release.

“... The working men and women of New Hampshire sent Chris Sununu to Concord to fight for them, and that’s exactly what he has done,” McQuillen said of the Newfields Republican. “From championing legislation that keeps our communities safe to recognizing there is more work to be done in fighting the opioid epidemic, the Professional Fire Fighters of New Hampshire shares the Governor’s vision for a safer, stronger New Hampshire.”

The endorsement was announced Wednesday morning at a fire station in Londonderry. The Professional Fire Fighters of New Hampshire represents current and retired firefighters, fire officers, paramedics and dispatchers from more than 40 local unions, according to the release.

Sununu, a former New Hampshire executive councilor, is seeking his second term as governor over challenges by Molly M. Kelly, a Harrisville Democrat, and Jilletta Jarvis, a Sandown Libertarian. Sununu ran unopposed in his party’s primary election earlier this month, ahead of the general election Nov. 6.

Both the N.H. Police Association and the N.H. Troopers Association endorsed Sununu over the summer.
