There are multiple recordings that provide evidence that the ADM and the deputy minister had actually given the minister and the minister's office updates as to what was happening at SDTC and the findings, whereas the minister himself has publicly stated that he had no idea what was going on between March and the end of September.
On top of that, there is even audio evidence that at the end of the reporting period, at which point the final recommendation was made to the minister, the reports and information were actually given to the minister verbally, at which point he asked for changes to the report and recommendations before it was officially registered.
