Riverside County Supervisor Manuel “Manny” Perez now has a motherlode of endorsements heading into the June 5 election, securing the the Mother of them all — that of the most prominent Democrat in the Coachella Valley — former U.S. Sen. Barbara Boxer.

In announcing her endorsement, Boxer released the following statement:

“Manuel Perez has dedicated his life to making the Coachella Valley a better place to live. At every stage of his career he has fought to expand access to healthcare, provide for our veterans, protect the most vulnerable among us, and make sure the same California Dream that he achieved is attainable for the next generation. Manuel’s inspirational personal story, devotion to community service, and progressive values make him the best choice for Riverside County Supervisor. I am looking forward to voting for Manuel Perez on Tuesday, June 5.”

Boxer, who resides in Rancho Mirage, represented California in the U.S. Senate between 1993 and 2017. Prior to election to the Senate, she served for ten years in the House of Representative.

Boxer’s endorsement is the second significant endorsement of the week. Earlier this week, Perez, who is seeking a four-year term on the Riverside County Board of Supervisors, earned the endorsement of the California Correctional Peace Officers Association.

CCPOA joins the Riverside Sheriffs’ Association and Cal Fire Local 2811 in backing Perez’s campaign.

In announcing their endorsement, CCPOA Chapter President Terry Hammon released the following statement:

“As an incumbent Supervisor, Manuel “Manny” Perez is a steadfast champion for keeping Riverside County’s families and neighborhoods safe. Throughout his career in public service, he has demonstrated the judgment, character, and work ethic needed to make an effective County Supervisor. The California Correctional Peace Officers Association are proud to join with local firefighters, sheriff deputies, and public safety leaders in supporting Manuel Perez for Supervisor.”

Eastern Riverside County is home to two state prisons: Chuckawalla Valley State Prison and Ironwood State Prison in Blythe. Thousands of CCPOA members live and work throughout the county, protecting the public while serving as state correctional officers and parole agents.

Founded in 1957, CCPOA is the labor union that represents corrections officers in California. Their mission is to promote and enhance the correctional profession, protect the safety of those engaged in corrections and advocate for the laws, funding, and policies needed to improve prison operations and protect public safety.

Perez is challenged in his bid by Jan Harnik, a member of the Palm Desert City Council.
