Proud to name Justina Salinas, owner of Araceli Farm in Dixon, as the 2025 Solano County Climate Crisis Champion! Her dedication to regenerative agriculture, water conservation, and native plant restoration makes her a powerful example of climate leadership in our community.
Proud to recognize the Clear Lake Environmental Research Center as the 2025 Lake County Climate Crisis Champion! Their work in wildfire prevention, environmental resilience, and climate action is making a real impact in our community. www.record-bee.com/2025/04/14/t...
April is #SchoolLibraryMonth—a time to recognize how essential our school libraries and librarians are in fostering literacy and a lifelong love of reading. Libraries have always been a place of inspiration and discovery, and I know how important they are for students across our district.

Residentes de Knight’s Landing: HOY, mi equipo estará presentando horas de oficina en persona de 4:30 p.m. a 6:30 p.m. en asociación con la oficina del Supervisor Ángel Barajas. (1/4)
Everyone—from insurance providers and homebuilders to consumer advocates and regulators—agree that my bipartisan Disaster Resiliency and Coverage Act will help reduce wildfire risk and make insurance more accessible and affordable.
Proud to name Chairman Anthony Roberts of the Yocha Dehe Wintun Nation as Yolo County’s 2025 Climate Crisis Champion. From wildfire mitigation to protecting 1,500 acres of sacred land, his leadership is making Yolo more resilient and sustainable for future generations.
Happy #EarthDay! For fifty-five years, we have celebrated this day to raise awareness for environmental issues and inspire action. As a life-long conservationist, I have and will continue to fight for our environment!
Trump’s tariffs are a hidden tax, costing families up to $4,600 a year. Congressional Republican cuts to SNAP, childcare, and health care are making things worse. I am working to lower prices — from prescription drugs to groceries to housing — and put working families first.
Pete Hegseth continues to handle our sensitive national security information recklessly. This isn’t just shameful, it is dangerous for our men and women in uniform. He must be held accountable. www.usatoday.com/story/news/p...
Deeply saddened by the passing of His Holiness Pope Francis. Pope Francis broke barriers as the first Jesuit and first Latino to lead the Catholic Church and he always reminded us that everyone has a role to play in caring for our neighbors and our planet.

26 years ago, 13 people were killed in a shooting at Columbine High School. Today, we honor their legacy and demand legislation that keeps guns out of the hands of people who are a danger to themselves and others.
