Masari contested the office of Katsina State Governor in the
2011 election under the platform of
Congress for Progressive Change. He lost the election to
PDP's Ibrahim Shehu Shema. In December 2014 he emerged as the governorship candidate of the
All Progressives Congress for the March 2015 elections. Aminu Bello was declared winner of the 11 April 2015
Katsina State governorship election, defeating Musa Nashuni, and was sworn in on 29 May 2015. Immediately after his inauguration, amid financial recession in the country, Masari accused his predecessor of literally stealing the state treasury after 2015 elections and a few days to handing power to his new government. This accusation along with similar financial cases amounting to N11 billion compelled
EFCC to invite and later charge Barrister Shema to court along with some of his cabinet members. Governor Masari also dissolved local government chairmen, who were all from the ousted party. On its part, PDP challenged the state in court for dissolving democratically elected local government chairmen. Aminu Bello Masari was elected for a second term as Governor of Katsina in the 9 March
2019 Katsina State gubernatorial election under the platform of
All Progressives Congress having polled 1,178,864 votes against Peoples Democratic Party's Senator
Garba Yakubu Lado's 488,621 votes. ==See also ==
