Gosh only two comments. I guess the Senate scandals and lack of action re no longer newsworthy  Its what we expect from them. 
So the head of some Senate Committee says it would be too costly to try and recoup the money. Well, seems to me that there is a little more than cost comparison. Its the fact these senators have been cheating the taxpayer, not doing their jobs, representing provinces they often never should have been appointed for...hello Queen  Pamela and The Puffster.
Also by not prosecuting these guys..its a signal to the rest of the gang..and using a criminal associated term to describe them is not a bad idea actually....it tell them that there are no consequences to their actions...and gosh...why be honesst when you can charge for personal trainers....pay fees to friends who ostnsibly do no work..use your senate seat to campaign for the party that appointed you....
Get rid of the senate. If man could land on the moon we can get rid of this bunh of losers. New ones included
