Some media queries that went unanswered by Senate communications department

OTTAWA - A selection of questions posed since May to the Senate's communications department by reporters at The Canadian Press that have so far gone unanswered:

— When did Senate Finance first indicate to the internal economy committee that it had concerns with Sen. Pamela Wallin's expenses?

— On which days was Sen. Mike Duffy claiming per diems? (Information not included in an independent auditor's report, but held by Senate Finance)

— How much has Sen. Pamela Wallin repaid to the Receiver General of Canada to date, and what precisely were the repayments for?

— Can you specify which of Wallin's claims listed by independent auditors as needing review were deemed to be acceptable by the internal economy committee and why? Why were others deemed unacceptable?

— What were the financial details that went into calculating the $90,000 total made by the committee on internal economy for Duffy's expense repayment?

— Can you confirm that Wallin must repay her travel expenses by Sept. 16? (Senate communications refused to answer question unless it was formulated in an email).
