Revenue Minister and P.E.I. Conservative MP Gail Shea isn't offering an opinion on whether fellow Islander Mike Duffy should resign from the senate as the upper chamber's expense controversy continues to unravel.

The former journalist resigned from the Conservative caucus on Thursday, a week after audit and Senate committee reports were released on his expenses, as well as those of Conservative Senator Patrick Brazeau and Liberal Senator Mac Harb.

Shea was shaking hands at the Nova Scotia Soccer Training Centre in Halifax on Monday to promote the federal government's tax breaks for Canadians.

She said she's been hearing from Islanders on the issue.

"Of course there are lots of questions because people do expect accountability and you know that’s something our government has stood for...we think it's very important," she said.

The senator’s spending scandal took another dramatic turn on Sunday when Nigel Wright, the prime minister’s chief of staff stepped down after writing a $90,000 cheque to re-pay Duffy's improperly claimed housing expenses.

Shea wouldn’t say whether she thinks Duffy should resign from the senate.

"Accountability when it comes to spending taxpayers’ dollars is very important.  The prime minister has made a statement on this issue and so I can't comment any further because I am not privy to the facts in this case," she said.

She said the conservative caucus is meeting on Tuesday.

Duffy announced last month that he had repaid, on March 25, about $90,000 claimed over the last three years for his Senate housing and living expenses.

He is one of three senators who have been at the centre of an external audit since December over expense claims.
