Sen. Mike Duffy is suing the Senate and the RCMP for the way they handled accusations about his expenses.

Duffy filed a claim in Ontario Superior Court on Thursday, seeking millions of dollars in damages and compensation for loss of income and benefits.

The claim alleges his suspension by the Senate was unconstitutional and that the RCMP were negligent in their investigation.

In a statement, Duffy said he and his family suffered stress and serious financial damage and that his lawsuit is as much about the future as it is about the past.
