The national assembly’s health committee this morning grilled health CS Cleopa Mailu and his principal secretary Nicholas Muraguri over the alleged scandal involving at least Ksh 3.2 billion at the ministry. In the latest parliamentary inquiry, the CS pointed the finger of blame to the ministry’s internal auditor claiming that the audit was conducted haphazardly. Muraguri on his part insisted that the auditor failed to counter check payments from cash office immediately they were made.
