Senator Dan Lang says that when the Auditor General of Canada’s review of Senate expenses is complete, he’s “confident that Yukoners will find that I have acted in good faith and in keeping with Senate policies and practices.”

Lang’s office issued a statement this morning in response to a CTV News story first aired Tuesday.

The story alleged he repaid money after auditors questioned him about a flight that appeared unrelated to Senate business.

Lang did not confirm that to CTV, nor did he confirm it to the Star this morning.

“Owing to the confidentiality agreement between the Office of the Auditor General and individual senators, I am unable to comment on the substance of the audit at this time,” Lang said in the statement.

The Office of the Auditor General declined to provide details about the confidentiality clause, or the audit itself.

“The work is ongoing, and any details regarding our scope, progress and methodology will not be discussed while the work is ongoing,” wrote spokesperson Ghislain Desjardins

“We do not speculate about audit findings, or how they will be presented.”

Auditor General Michael Ferguson is reviewing senators’ expenses between April 1, 2011, to March 31, 2013. The audit began in the fall of 2013, and is expected to be completed by the end of the year.

Lang said the audit of his office has begun.

It’s his understanding, he said, there are multiple phases to it: first, the auditor general raises “general questions” as a result of its first review of a Senate office.

Second, the auditor general requests a meeting with the office to “to address any areas requiring further clarification.”

In the third phase, Ferguson would provide his findings in the form of a letter and hold a discussion with the senator’s office, Lang said.

Lastly, the auditor general “would seek sign-off from the Senator with respect to any findings.”

Lang said his office has completed the first phase of the audit, and responded “in full” to Ferguson’s questions last December.

“At this point, and to the best of my understanding, the Office of the Auditor General has yet to commence the second phase of the audit of my office,” Lang said.

The auditor general’s website states that a meeting with each senator is held when the audit of his or her expenses begins.

Citing anonymous sources, CTV News reported that at least 40 current and former senators have received confidential letters from Ferguson about questionable expense claims.

One was asked to account for more than $100,000, the network reported.

When approached by CTV Ottawa bureau chief Robert Fife on Tuesday, several senators declined to comment, some citing a confidentiality clause in the audit.

Meanwhile, the RCMP levelled new allegations against suspended senator Pamela Wallin today.

They allege she fabricated Senate business in order to get reimbursed for personal expenses.

No charges have been laid.

RCMP have charged former Conservative senators Mike Duffy and Patrick Brazeau, as well as retired Liberal senator Mac Harb, with making fraudulent expense claims.

Duffy’s trial will begin next Tuesday in Ottawa.
