The U.S. Chamber of Commerce, the nation's largest business coalition, endorsed former Hewlett-Packard CEO Carly Fiorina (R) in the California Senate race.

The Chamber's national political director, Bill Miller, cited Fiorina's business acumen in his endorsement, saying her experience could help fix the country's economic woes.

"We’re endorsing Carly because she understands the challenges businesses are facing and will stand up for the people of California during these tough economic times," Miller said in a statement. "She is an invaluable leader who has a common-sense approach to job creation and getting America back on the road to recovery."

Fiorina is running to unseat Sen. Barbara Boxer (D-Calif.), the chairwoman of the Senate Environment and Public Works Committee.

As the head of the panel, Boxer has been a strong advocate of cap-and-trade climate change legislation. The Chamber caused a stir last year when it lost several high-profile companies due to its opposition to similar legislation passed in the House.

The Chamber of Commerce has said it would support legislation that has a lesser impact on businesses than several current proposals.

Boxer's seat is a top Republican target this cycle. Several recent polls show the senator leading Fiorina by single digits.

To tout the group's endorsement of Fiorina, Miller will travel with Fiorina on a two-day, six-city tour in California to highlight "her record of supporting the state’s businesses and workers."
