What does Grant know?

Duncan Garner writes:

The heat is seriously on Grant Robertson to tell us what he knew about the sexual assault allegations, when he knew it, and who he shared the information with.
What happened to this self-labelled, so-called ‘most open and transparent’ Government? How much longer can Grant seriously hold this unsustainable position of “sorry not going there”.
He can’t. Silence is not golden, and silence shouldn’t be rewarded.

Grant will duck and weave but, at some stage, he’ll have to be forthcoming.

I predict Grant will never ever say what he knew and when. To do so would be fatal.
