In February 2016, while serving as provincial head of the Women's League in Mashonaland East, Chinomona was suspended from ZANU–PF in a vote of no confidence by the party's provincial coordinating committee. The reason given was that she had been neglectful in facilitating a planned trip by a group of Women's League members to Harare to meet President Robert Mugabe. However, the real reason was reportedly her association with Emmerson Mnangagwa's Lacoste political faction within the party. The influential party member Sydney Sekeramayi reportedly intervened on her behalf. After the vote of no confidence, she continued to serve in the Women's League, but this time as political commissar. After the 2017 Zimbabwean coup d'état, she clinched the Women's League's top office as secretary. As secretary, she is also automatically a member of the party's politburo.
