Five former attorneys general are calling for the RCMP to investigate "disturbing pattern of events" detailed by Jody Wilson-Raybould. In a letter to the RCMP, former Conservative justice ministers and attorneys general Peter MacKay (2013 to 2015 and Douglas Grinslade Lewis (1989 to 1990) and provincial attorneys general Jonathan Denis (Alberta, 2012 to 2015), Cecil Clarke (Nova Scotia, 2007 to 2009) and the NDP's Colin Gabelmann (B.C., 1991 to 1995), say Wilson-Rayboud, in her testimony to the justice committee earlier this week, exposed political interference prohibited under the Criminal Code. MacKay served as justice minister under former Conservative prime minister Stephen Harper. "'Undue pressure' was placed on former Attorney General (Wilson-Raybould) by political actors urging her to exercise her authority to overrule the director of public prosecutions," says the letter, dated Feb. 28.

It references a section of the Criminal Code that prohibits attempting to obstruct, pervert or defeat the course of justice. "We believe that there are reasonable and probable grounds to suspect that the conduct of the Prime Minister's Office has crossed that threshold," the letter says. "In our shared view, ordinary Canadians ... have been charged under these sections with much less evidence." On Wednesday, Wilson-Raybould detailed a "consistent and sustained effort" by Prime Minister Justin Trudeau and top political staff to "inappropriately" interfere in her role as justice minister and attorney general to secure a deferred prosecution agreement and avoid a trial on corruption charges for Quebec-based engineering company SNC-Lavalin.
