Not every senator, however, is staying silent.
Newfoundland And Labrador Senator Fabian Manning joins "22 Minutes" Tuesday night and host Mark Critch doesn't take it easy on him.
After suggesting it's like a "crack house" in the upper chamber, Critch takes on Duffy's confusion about where he lives and Wallin's sky-high flight expenses.
Our favourite moment? When Critch says senators are spending their days "eating caviar and drinking swans' blood." Just try to un-imagine that image.
This Hour Has 22 Minutes airs on CBC TV Tuesday nights at 8:30 p.m. Catch more clips of the show on Facebook and Twitter.
