Yes, to begin with.
Mr. Clark was not there at the time of the events, even though he was still working at the PMPRB. When you want to have somebody intervene who was not there at the time of the events, it's because you want to get to the bottom of things. My view is that the issue now before us is why people resigned and what the minister's involvement with these resignations was.
There are also two contradictory letters of resignation. We therefore need to work with the main players, and only afterwards, for further clarification, invite other people to appear.
