Between 2008 and 2009, Gachoka was the Chief of Protocol in the O ce of the Prime Minister. Before that, he was Raila Odinga’s political aide, a position he had held since 2005. In the late 1990s, Gachoka published an infamous tabloid, Post on Sunday.
The tabloid was known for screaming headlines and bareknuckle approach to investigative journalism. In February 1998, Gachoka was charged with criminal libel by the Attorney General on behalf of the Kenya Court of Appeal.
He was convicted and jailed incommunicado for 74 days before being released after a campaign of sustained pressure by civil society and the international community.
The court had sentenced him for six months for contempt of court and subjudice. His publication folded shortly after the court slapped Post on Sunday with a fi ne of Sh1 million.
In 2001, Gachoka failed miserably when he contested for the Juja Constituency parliamentary seat after he garnered only 200 votes in the nominations, before decamping to Safina party where he only managed to garner 1,000 votes in the General Election.
