Republicans running for the U.S. House of Representatives in New York on Tuesday announced endorsements from key labor unions as the party hopes to build a working majority in Congress this fall. 

Dutchess County Executive Marc Molinaro won the backing of the Civil Service Employees Association, the state's largest public workers union, in his campaign for the newly drawn 19th Congressional District in the Hudson Valley. 

Molinaro faces Democrat Josh Riley in the November general election. 

"Thank you CSEA for your support," Molinaro said. "I’ve always fought for our hard working families and know the incredible work CSEA employees do all across New York."

Incumbent Republican Rep. Claudia Tenney, meanwhile, was endorsed by the New York State Law Enforcement Officers Union. Tenney is running for the newly drawn 24th District against Democrat Steve Holden. 

 “The New York State Law Enforcement Officers Union, Council 82, AFSCME, AFL-CIO (Council 82), is honored to endorse and stand with you in your re-election for the 24th Congressional District," said Council 82 President said Ronald Walsh. "As you know, Council 82 represents over 3,000 Police Officers, Deputy Sheriffs, County Correction Officers, State Correction Lieutenants, Emergency Dispatchers, and other Public Safety personnel across New York State, including members who live and work in the 24th Congressional District. Our endorsement of you recognizes your strong and unwavering support and for law enforcement, veterans, and military families.” 

New York is considered a key battleground state for control of the narrowly divided House of Representatives this November.
