[3] In recognition of his service to Nigeria, Aminu Masari received the National Award of honour of Commander of the Federal Republic (CFR) in 2005, by His Excellency, Chief Olusegun Obasanjo GCFR.

Masari contested for the office of Katsina State Governor in the 2011 election under the platform of defunct Congress for Progressive Change.

[5][6] Aminu Bello was declared winner of the 11 April 2015 Katsina State Governorship election, defeating Musa Nashuni.

Immediately after his inauguration, amid financial recession in the country, Governor Masari accused his predecessor of literally stealing the state treasury after 2015 elections and a few days to handing power to his new government.

[8] 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.
