Gerald Butts had his say on the SNC Lavalin affair this morning when he was scheduled to appear before the Commons Justice Committee in Ottawa.

The longtime friend and former Principal Secretary to Prime Minister Justin Trudeau tried to counter damaging testimony last week by former justice minister Jody Wilson-Raybould. Wilson-Raybould testified that Butts was among a group in the PMO who tried to pressure her into going easier on the Montreal engineering giant.

At the same time Justin Trudeau is said to be weighing whether to deliver an expression of contrition or a more detailed statement on the SNC Lavalin controversy in a bid to contain a political crisis that has already cost him two cabinet ministers and his top aide.

The SNC Lavalin storm is affecting the way voters are thinking about the Prime minister.
