RCMP documents released last week allege Conservative Sen. Irving Gerstein tried to stop the audit in its tracks by calling a partner at the firm.
The auditors are expected to be asked about the allegations, which have not been proven in court.
The opposition parties repeatedly asked Prime Minister Stephen Harper in the Commons yesterday why Gerstein hasn't been relieved of his duties, which include sitting on the Senate banking committee and being in charge of donations to the Conservative party.
