I think it's highly unusual.... Granted, I don't have the experience level of many members of this committee, but I think it's highly irregular, if not unusual and not as per appropriate committee protocol, for any member other than the chair, working with the clerk, to issue a formal invitation to any witness—in this case Mr. Viersen.
I don't think it's incumbent upon me, although he's a colleague and a member of the Conservative caucus.... I think it's a requirement of the chair, working in concert with the clerk, to issue the formal invitation.
