Tenure

On July 6, 2021, O'Laughlin visited the Schuyler County Courthouse in Lancaster. The goal of the visit was to let residents talk about current Missouri issues.

On joining the Senate, O'Laughlin was initially a member of the conservative caucus, but left in 2021 due to their disruptive tactics. In 2023, she was the first woman elected as majority leader of the Missouri Senate. In 2025, she was the first woman to serve as president pro tem.

Abortion

In 2025, O'Laughlin supported a measure to reverse a constitutional amendment passed by a majority of Missouri voters the previous year. As pro-tem, she facilitated the interruption of oppositional filibuster using an uncommon procedural move. O'Laughlin told media that the measure was a compromise for officials who campaign on opposing access to abortion.
