My perspective on this—which I think is borne out by what I conveyed in my statement—is that when the political level of government is made aware of rumours or even allegations, I believe they have a responsibility to convey them to officials immediately and ensure that the information, whatever it may be, is pursued and investigated. If there are findings, they should be reported back to the political level of the government for further decision if necessary.
That's how I acted in 2015 and I believe that's entirely appropriate.
