  • When Nielsen was selected as Senate Republican Leader in 1983, he was 39 years old, making him the youngest known person to ever hold that office.
  • Marilyn was a delegate to the 2020 Republican National Convention.
  • THE LAST REPUBLICAN: During the final week of the 2019-20 session, as the COVID epidemic raged statewide, Nielsen was the sole Republican Senator permitted to attend the floor session after the rest of his caucus was quarantined following exposure to a Senator who had later tested positive.
  • NONCONSECUTIVE SENATE TERMS: In 2013, Nielsen became the first person to return for a non-consecutive term in the State Senate in 43 years. The last had been John W. Holmdahl (who returned to the Senate in 1970). In 2015, Sharon Runner was elected to the Senate in a special election, becoming the second.
  • LEGISLATION: Author of SJR 10 (2022) which would provide California's ratification for the the First to Twelfth Amendments to the United States Constitution.
  • LEGISLATION: Author of SCR 43 (2017), which would have conferred the position of Legislative Historian for the first time since the death of Don A. Allen Sr., who held the title from 1967 to 1983. The bill was held in the Rules Committee.
  • QUOTABLE: After his State Senate swearing-in ceremony in 2013, Nielsen noted "Taking that sacred oath again, where I'll now again have the opportunity to serve in this honorable body, I wanted to reflect on how special this honorable body is... I've had the pleasure, in my years, or representing 21 different California counties and three of the former state capitals; Vallejo, Benicia, and Sacramento and succeeding a fellow whose home I went up to quite often in Sonoma (he wasn't around at the time) General Mariano Vallejo, who served in this house, first elected in 1849. Those are the kind of people who have inhabited this Chamber, and the thing that is special about the Senate."
  • NATURAL DISASTER (LARGEST WILDFIRES): The largest and third-largest wildfires in California history (the August Complex fire in 2020 and the Mendocino Complex fire in 2018) occured primarily within State Senate districts represented by Mike McGuire and Jim Nielsen and and Assembly Districts Jim WoodJames Gallagher, and Cecilia M. Aguiar-Curry.
  • NATURAL DISASTER (DEADLIEST WILDFIRE): The fourth-deadliest wildfire in California history (the Tubbs Fire in October 2017) burned nearly 15,000 acres and killed 22. It occured primarily within State Senate districts represented by Mike McGuire and Jim Nielsen and Assembly Districts Jim WoodCecilia M. Aguiar-Curry, and Marc Levine.
