Former Los Angeles Mayor Antonio Villaragosa, a candidate for California governor in 2026, criticized former Vice President Kamala Harris and former U.S. Secretary of Health and Human Services Xavier Becerra on Tuesday criticized accomplices for covering up former President Biden's cognitive abilities during his tenure.

Villaraigosa said the actions partly resulted in President Trump's victory in November's election. Becerra, who previously served as California attorney general, is also running for governor, and Harris is considering playing. All three are Democrats.

"At the highest level of our administration, those in power have intentionally conspired or spoke completely of the system's cover-up to keep Joe Biden's spiritual decline away from the public," Villaraigosa said in a statement. "Now, we have begun to learn about cover-up, including two California politicians who have served as California attorney general - one running for governor, another considering running for governor. Voters should know the truth, what Kamala Harris and Xavier becerra are, when, when, and why not?"

Villaraigosa's remarks are based on excerpts from "Original Sin: President Biden's Decline, Coverage, and Disastrous Choice" written by CNN's Jake Tapper and Alex Thompson of Axios and published publicly on Tuesday.

The book relies heavily on anonymous sources, believing that Biden’s confidant and inner circle have made his state worse, thus achieving a Republican victory in the 2024 presidential election.

The book portrays Biden as a decade-long decline and believes a group of political advisers and his family have masked their situation to voters.

"Kamala Harris and Xavier Becerra were sworn in and protected to protect the American people, but Kamala Harris repeatedly said that Biden and Becerra turned a blind eye," Villaraigosa said.

The former president revealed on Sunday that he published a "primitive sin" shortly after being diagnosed with an aggressive form of prostate cancer.

According to the New York Times, one example of Biden's decline in perceptions cited is that he confuses Bekra with Homeland Security Secretary Alejandro Mayorkas.

When asked to respond to the attack in Villara Lagoza, Bebera did not resolve the incident, but expressed good wishes to the former president and his family as Biden began treatment. He also defended the deal with the former president when he served as head of U.S. health.

“I met President Biden in a situation where important decisions need to be made and executed with the HHS team,” Bebera said in a statement. “It’s clear that the president is getting older, but he made it clear that task: running the world’s largest health agency, expanding care for more Americans than ever before, reducing the cost of prescription drugs, and lifting us out of the global pandemic. We delivered.”

On Tuesday afternoon, the delegate who tried to reach a deal with Harris failed.
