Mike Duffy Takes Medical Leave From Senate Amid Health Troubles

OTTAWA - Former Conservative senators Mike Duffy and Pamela Wallin will each face motions in the Senate that would see them suspended without pay, says a Conservative source familiar with the motions.

Duffy is at the centre of an ongoing Senate scandal involving improper housing expense claims, while Wallin has been under fire for disallowed travel expenses.

Duffy has asked for a medical leave under doctor's orders after suffering a recent bout of unstable angina that resulted in a two-day hospital stay.
