Breese-Iverson joined the
80th Oregon Legislative Assembly after being appointed on August 8, 2019 to replace
Mike McLane. She owns a real estate business in
Prineville. She had previously worked for former Oregon State Senator
Ted Ferrioli and former Oregon State House Speaker
Karen Minnis. She won re-election in 2020 by a large margin, 73.5% of the vote. Breese-Iverson has cast doubt on the validity of the 2020 presidential election results. On December 11, 2020, Breese-Iverson and 11 other state Republican officials signed a letter requesting
Oregon Attorney General Ellen Rosenblum join Texas and other states contesting the results of the
2020 presidential election in
Texas v. Pennsylvania. Rosenblum announced she had filed in behalf of the defense, and against Texas, the day prior. In 2021, Breese-Iverson sent a letter to Secretary of State
Shemia Fagan, requesting a "full forensic audit" of Oregon's 2020 elections. In November 2021, she signed a letter along with other Republicans around the nation calling for an audit of the 2020 election in all states. She served in this role until September 2023 when she stepped-down due to rumors of her being unseated. She was replaced by
Jeff Helfrich. Following the
Standoff at Eagle Pass, Breese-Iverson signed a letter in support of Texas Governor
Greg Abbott's decision in the conflict. == Personal life ==
