Treasury CS Henry Rotich was on Tuesday grilled in connection with construction of multi-billion-shilling dams amid claims of kickbacks. His Tourism counterpart Najib Balala has been questioned with regard to a contract awarded to a US tour firm.
Mr Balala also appeared before MPs on Thursday to shed light on the swirling claims of impropriety.
Matters were compounded on Thursday when the Senate amended the report on the maize importation scandal and recommended two more CSs and several principal secretaries be held culpable for the importation of maize that destabilised the sector and impoverished farmers.
The Senate, in August last year, established an ad hoc committee on the maize scandal and recommended that Mr Rotich and then Agriculture CS Willy Bett be held responsible for the mess.
But when debate on the report came up on Thursday, senators voted that all government officials who sat in the inter-ministerial committee on food security be held responsible.
Among the members are Interior CS Fred Matiang’i and his Agriculture counterpart Mwangi Kiunjuri.
Dr Matiang’i also had a close shave when MPs accused him of having benefited from the Ruaraka land scam. A Parliamentary report linking him to the scandal was rejected by the House.
Health CS Sicily Kariuki has also survived despite parastatals under her watch such us the National Hospital Insurance Fund (NHIF) facing claims of massive theft of public money.
