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.[2] 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.[2] However, the real reason was reportedly her association with Emmerson Mnangagwa's Lacoste political faction within the party.[2] The influential party member Sydney Sekeramayi reportedly intervened on her behalf.[2] After the vote of no confidence, she continued to serve in the Women's League, but this time as political commissar.[2] After the 2017 Zimbabwean coup d'état, she clinched the Women's League's top office as secretary.[2] As secretary, she is also automatically a member of the party's politburo.[2]
