RCMP are looking into expenses claimed by Senator Mike Duffy.

Police documents show Peter McQuaid, Wayne Hooper and Jason Lee all performed consulting work for Duffy between 2009 and 2012, and were paid through his senate office expense budget.

RCMP say the contracts were for relatively low amounts, $3,000 or less, and while "none provided a tangible work product to Duffy," all three are or were legitimate consultants who submitted detailed invoices including hourly rates for their work.

The three Island men were interviewed last month.

RCMP are contrasting those cases with that of Gerald Donohue, a former television station technician described as a friend of Duffy's, who was paid nearly $65,000 over four years for what police describe as "little or no apparent work."

Police are seeking bank records to try to trace where that money went.
