There's word Prime Minister Stephen Harper's former chief of staff, Nigel Wright, senators and Conservative members of Parliament have received subpoenas to testify at the trial of suspended Sen. Mike Duffy.
The CBC quotes sources familiar with the Crown's witness list as saying David van Hemmen, Wright's former executive assistant, and Benjamin Perrin, who acted as the prime minister's lawyer, have also been called to testify.
Duffy, a former Conservative senator, faces 31 charges, including fraud, breach of trust and bribery. The last charge deals with a $90,000 cheque Duffy received from Wright to reimburse the Senate for challenged expense claims.
The CBC says senators called to testify include Marjory LeBreton, the former government leader in the Senate, David Tkachuk and Carolyn Stewart-Olson.
It adds that Conservative MPs, including Ontario's Barry Devolin, will be asked to testify about Duffy's fundraising efforts on behalf of the party.
The trial is scheduled for 41 days, from April 7-May 12 and June 1-June 19.
