The public was last week treated to blame game between the Ministry of Health top officials and the management of the Kenya Medical Supplies Agency over what happened in regard to the use of Covid-19 funds.
As this happened the country's Covid-19 death toll inched closer to 600.
The National Assembly Health committee and the Senate Ad hoc committee on Covid-19 Situation in the Country are separately probing the alleged procurement irregularities at Kemsa.
The Senate heard that ministry officials pressed Kemsa to procure items running into billions of shillings at inflated prices in disregard of procurement laws.
Kemsa chairman Kembi Gitura and suspended CEO Jonah Manjari appeared to shift blame to their bosses at the Ministry of Health.
Health CS Mutahi Kagwe is this week expected to appear before the National Assembly Committee on Health to shed more light on the scam.
The Senate committee, on its part, has indicated it will have a session with the CS next week after gathering more information from Kemsa officials.
What the country is now being treated to is duplication of work by the two committees of Parliament. Instead of parallel investigations, the two committees should work hand in hand.
Rather than grilling the same officials separately, it would be more logical if the investigations are harmonised.
This will give Parliament a chance to cover more ground and come up with one detailed and actionable report.
The investigations by the Ethics and Anti Corruption Commission should proceed independently.
