Arthur was first elected to the Missouri House in 2014 and took office in 2015.[3] In the 2018 special election for Missouri State Senate District 17, which covers most of Kansas City suburb Clay County,[5] Arthur defeated her Republican opponent, fellow Missouri state representative Kevin Corlew, by a 20-point margin. She replaced Republican Ryan Silvey, who won re-election to the seat in 2016 by 20 points, before he stepped down to join Missouri's public service commission. Republican presidential candidates Mitt Romney and Donald Trump had each won the district by four points.[6]
Arthur resigned from the Missouri Senate in July 2024 after being appointed to the Missouri Labor and Industrial Relations Commission.[7][8]
