Brown gained a reputation for knowing what was occurring in the state legislature at all times. In 1992, he gave $1.18 million to the Democratic Party to help with voter registration and several campaigns, some of which was from contributions from tobacco companies and insurance companies. As Speaker, he worked to defeat the Three Strikes Law. Critics have claimed Brown did not do enough to raise the legislature's ethical standards or to protect the environment. During his time in Sacramento, he estimates he raised close to $75 million to help elect and reelect state Democrats.
