Blair and Lucki to testify about allegations of interference in RCMP N.S. mass shooting investigation

A month after the controversy first made headlines, key players will be testifying Monday as part of a parliamentary probe into allegations of political interference in the RCMP's investigation of the Nova Scotia mass shooting.

First up as part of today's Public Safety and National Security Committee's hearing into the allegations that federal officials put pressure on police in the aftermath of the worst mass shooting in Canadian history to help push forward a new gun ban, will be Emergency Preparedness Minister Bill Blair.

Blair, who during the time period in question was Canada's public safety minister, will be accompanied by Rob Stewart, deputy minister of the Department of Public Safety and Emergency Preparedness.

Then, RCMP Commissioner Brenda Lucki and Deputy Commissioner Brian Brennan will testify, as will a few other current and former RCMP officials.

The special summer meeting of the committee of MPs was the result of a pre-summer House of Commons hiatus vote, prompted by the opposition parties' desire for the government to provide a full airing of the facts as they relate to the matter.
