In 2015, Cox, now a college graduate, was hired by the office of Representative Sam Graves as a legislative correspondent and staffer. She currently works at the United States Chamber of Commerce, a business-oriented lobbying firm. She also worked for the Sports & Entertainment Network as an anchor and analyst. In 2016, Cox competed in Miss District of Columbia, which selects a representative to compete in the Miss America pageant, and finished as Second Runner-Up. She competed as Miss Missouri in the 2016 Miss Earth United States contest. Cox competed again in the Miss District of Columbia pageants in 2017 and 2018, and each time again finished as Second Runner-Up. Cox was part of the Washington Capitals’ cheerleading team, the Red Rockers, from 2017 through 2019. In 2019, her final year of eligibility, Cox won the Miss District of Columbia title. At the Miss America 2020 contest, Cox was a finalist for the Women in Business Scholarship awards. After the contest, Cox posted a video in which she alleged that the Miss America Organization and NBC tried to prevent her from mentioning in her introduction speech that she is a rape survivor nor allowed her to speak about her social impact initiative, Silence Is Not Compliance, which seeks to educate women about, and prevent, sexual assault. Miss America responded to the allegations, stating that it was specifically the website of Silence Is Not Compliance that Cox was prohibited from mentioning, not larger content of her prepared remarks.

Cox attended La Salle High School, and at the age fifteen was awarded a full scholarship to Clark University. She graduated both Clark University and Mountain View High School in 2012. During 2011 she also studied engineering at Vanderbilt University. After obtaining her Associate degree, she attended the University of Missouri, studying communications and political science and graduating in 2014 with a Bachelor’s and Master’s in Public Administration.

The recording process for her album, which would be titled One Girl, took place in Nashville over the course of two years. Halfway through the process, Cox converted to Christianity. Although her lyrical focus changed after her conversion, she opted to keep the pop songs she had already recorded, as she felt that those songs could reach an audience that would not listen to Christian music. The album was released in 2011 through Red Hammer Records. In 2014, Cox released a second EP, Erase It, independently. From 2012 through 2014, Cox worked as a news anchor and producer at KOMU-TV.
