OTTAWA - A Liberal senator has repaid almost $31,400 in dubious expense claims which were detailed in a special arbitrator's report.

Senate records show Sen. Colin Kenny has paid expenses that former Supreme Court justice Ian Binnie deemed unjustified in his report released last month.

Binnie found that the questioned trips included overnight stays that didn't appear necessary and were sometimes scheduled around holidays with friends, time with family and even a suit fitting in Toronto.

Kenny's expenses were first flagged by the auditor general last year and sent to the RCMP for review.

Kenny says he won't make any comment until a final resolution of all issues.

His repayment leaves 14 current and former senators still on the hook for more than $636,000 in improper expenses first flagged by the auditor general last June.
