Trish Munro was elected to the Livermore City Council in 2018, and was appointed as Vice-Mayor in 2020.

• While running for Council in 2018, Munro accepted $2,000 from unions – $500 from IBEW 595 Joint Apprenticeship Training Council, $500 from International Brotherhood of Electrical Workers union, and $1,000 from the Sheet Metal Workers union.

• Despite the known contamination of the proposed Eden Housing site, in May 2021 Munro voted to declare it exempt from the California Environmental Quality Act. When challenged on it in June in a City Council meeting, Munro said that city staff had “completely debunked the idea,” and talking about it “wastes our energy and it wastes money and it’s a non-issue,” labeling such claims “propaganda.” In August, the San Francisco Regional Water Quality Control Board called the city’s proposed cleanup for the site “neither appropriately justified nor acceptable” and began a new round of testing of the site.
