July 24, 2013- "The RCMP's investigation into Senator Mike Duffy's expenses and the cheque Nigel Wright wrote to cover them has led to the Prime Minister's Office. A senior government source confirmed Wednesday that the RCMP has contacted the PMO and said it is assisting with the investigation. Wright was Harper's chief of staff who resigned after the secret $90,000 payment was revealed. He's not the only one who has left the PMO in recent weeks. Chris Woodcock, one of the people who knew about the cheque according to an affiadavit filed by the RCMP, left his job as director of issues management last week. Benjamin Perrin, who worked as a legal adviser in the PMO and is also named in the affidavit, is also gone. He left his job a few months ago and teaches law at the University of British Columbia. The RCMP met with Wright's lawyers on June 19 and details of their discussion are contained in court documents. http://bit.ly/13EZoSI
