There are allegations of a cover-up in the senate after word that Senator Pamela Wallin is being audited for $320,000 dollars in travel expenses over the last three years.

It’s claimed that many of those trips were to Toronto where Wallin owns a condo even though she represents Saskatchewan.

The NDP now wants the RCMP to get involved.

If it weren’t for the media, New Democrats said we never would have known that an independent audit firm is looking into Wallin’s travel.

This is only the latest in a string of senate investigations and the NDP’s Charlie Angus said we need to take it to the next level.

“The allegations are about falsifying documents, falsifying claims, we don’t know how many senators are involved, are there other secret investigations going on? I think it’s time that the police were brought in,” Angus said.

Angus said the police need to get involved because this is a lot of money, it’s one of a series of investigations on the misuse of taxpayers money, and we don’t know how many other secret audits there are.

“If you have a mouse in your house, a mouse in your kitchen, there’s more than one so you have to set a lot of traps to deal with them,” Angus said.

The Senate chose not to go public with this investigation and while the NDP said that’s a cover up, one of Wallin’s colleagues, Senator Gerald Comeau said that’s how it works.

“Such audits are part of the ongoing work that they do,” Comeau said.

But there is a lot of taxpayers cash involved in this case and if it’s been misused, police need to look into it.

That’s the feeling of NDP Leader Thomas Mulcair who points out this is one in a series of issues within the red chamber.

“The fundamental question is can the senate be trusted to investigate itself, because when we were asking yesterday how many were under investigation, they forgot to mention her but it turns out she was already undaer investigation at that time. The public has a right to know what’s happening with this body,” Mulcair explained.

Wallin has defended herself in an op-ed in The Globe and Mail, saying most of her travel was to her home province of Saskatchewan adding last year she spent 168 days there.

In addition to Wallin, senators Patrick Brazeau, Mike Duffy and Mac Harb are being investigated for possible abusing the housing allowance system for tens of thousands of dollars.
