Bulawayo Speech Walkout
During the "Meet the People" rally held by the then incoming Women's league Secretary Grace Mugabe at Amazulu Sports Club in Bulawayo, she covered up a massive walk out by the people from the stadium presumably as a sign of demonstration against the first lady. The people are said to have marched out of the stadium whilst the first lady was in the middle of her speech. This was generally viewed as resistance to the first lady.  Muchena attracted attention when she attempted to justify the walk out by the angry electorate. She argued that the people went on to receive food donations which were being distributed simultaneously with the first lady's speech. It was clear that Muchena had made efforts to explain resistance by the people of Bulawayo most of whom are generally believed to be sympathetic to the opposition the Movement for Democratic Change.

Demotion from Government
Muchena was part of the so-called Mujuru loyalists who were fired from government by Robert Mugabe in 2014. The Mujuru loyalists were accused of taking part in a plot led by the then vice president Joice Mujuru to unconstitutionally remove president Mugabe from power. Muchena was believed to have worked closely with the outspoken former ZANU PF chairman for Mashonaland east province Ray Kaukonde. Muchena was fired together with other senior party members such as Nicholas Goche, Didymus Mutasa, Rugare Gumbo, Jabulani Sibanda and Francis Nhema. She was replaced by Oppah Muchinguri who was generally viewed as loyal to Mugabe. 
Expulsion from ZANU-PF
Muchena was expelled from the ZANU-PF party on 21 May 2015. She faced the axe together with six other senior members from different provinces. This followed her initial sacking as the minister of higher and tertiary education. She was also dismissed from the party structures before the subsequent expulsion. The dismissal was believed to be an ongoing agenda by the ZANU-PF party to eliminate those believed to be loyal to the former vice president Joice Mujuru.
