Does Ray Novak talking to Bob Fife really matter?

CTV ran with breaking news that Bob Fife had tracked down PMO Chief of Staff Ray Novak. Novak said what has been said all along, he did not know about the payment and did not read the email. While hosting on 580 CFRA in Ottawa, Brian asked the audience of the CFRA Nation if this really is that important? It speaks nothing to the guilt or innocence of Mike Duffy who is on trial. It is a question of who knew what in a scandal where the taxpayers got their money back.
