Lawyer Donald Bayne said at a press conference Monday that Duffy's living expenses were "cleared from Day 1" by then Senate government leader Marjory LeBreton's office,and when they later became controversial, the senator was pressured to take a deal from the PMO.

At Issue panelist Andrew Coyne called Bayne's press conference an "extraordinary spectacle" that contained a "strong whiff of blackmail."
