Who is currently the Governor of California?

Gavin Newsom is currently the Governor of California, having taken office on January 7, 2019. His administration has focused on various issues, including healthcare reform, housing affordability, and environmental policies. Newsom previously served as the Mayor of San Francisco and the Lieutenant Governor of California, bringing extensive political experience to his role as governor.

In contrast, Jerry Brown, who served as the governor of California for four terms, completed his last term in early 2019, just before Newsom assumed office. Kamala Harris is currently serving as Vice President of the United States, and Arnold Schwarzenegger, who was governor from 2003 to 2011, is a former actor and not active in California's current government. Thus, Newsom is the correct answer, reflecting California's current leadership.
