RENO, Nev. (AP) — Dean Heller and Shelley Berkley are touting business endorsements in their heated Nevada U.S. Senate race.

Heller on Thursday was endorsed by the U.S. and Reno-Sparks chambers of commerce. A Republican, Heller was appointed to the Senate last year and is seeking election to a six-year term in November.

During a stop in Sparks, former U.S. Education Secretary Margaret Spellings now with the U.S. Chamber of Commerce said Heller is committed to free enterprise principles that drive economic growth and job creation.

Berkley is a seven-term Democratic congresswoman from Las Vegas. Her campaign released a list of small business owners supporting her candidacy, including a Republican business owner in Las Vegas.

Businesswoman Maggie Arias Petrel praised Berkley’s support of the Small Business Jobs Act, providing tax breaks to small businesses.
