[2] In 2002, at the age of 22, Kang'ata made history when he was elected as a Councillor for Central Ward in Murang'a Municipal Council.

He chaired Murang'a Municipal Council Town planning Committee, and he helped recover grabbed public land from powerful persons, including Mumbi stadium.

In 2012, Kang'ata became famous nationally after he defended Rebecca Kerubo, a security guard who was allegedly assaulted by the deputy Chief Justice Nancy Baraza.

[3] In 2013, Kang'ata contested for the Kiharu parliamentary seat on a TNA ticket, which he won after receiving 63,148 votes and defeating nine rivals.

[5] In 2015, Kang'ata fired three members of the local CDF committee over what he termed as misappropriation of funds meant for bursaries.

[7] In August 2016, Kang'ata filed a petition in the National Assembly accusing KRA enforcement officers of corruption which led to the availability of fake alcoholic drinks in the market.

[8] In 2015, Kang'ata was nominated for the Mzalendo Trust People's Shujaaz Award, given to lawmakers who championed issues of public interest in both the National Assembly and the Senate.

[11] In the same year, Kang'ata was also awarded by Central Kenya Forum for Peace for best management of Constituency Development Fund (CDF) and investing in domestic water projects.

The handshake came at a time when the political tensions in the country were at its peak after the 2017 General Elections disputed by the opposition culminating into a mock swearing-in of Raila Odinga on 30 January 2018 as the 'People's President.

'[18] Kang'ata is now considered to be a victim of the prophecy of fellow Senator and lawyer James Orengo, that the government eats its own children.

For instance, in 2014, surprisingly, Kang'ata was quoted as demanding for scrapping of the senate, claiming that it duplicated National Assembly tasks.

[22] Kang'ata's win resulted in a bitter exchange of harsh words with his close rival, with each accusing the other of rigging.

[24] After being sworn, Kang'ata, along with Nairobi's Johnson Sakaja, Kimani Wamatangi (Kiambu) and Nakuru's Susan Kihika applied for Gitura's old Senate Deputy Speaker seat.
