It's Trudeau's albatross because he didn't try to stop it in any way.  Just like the Saudi arms deal is on him because he chose to go with the flow and happily take the revenue.  Plus, it was 5 years of Liberal govs before the 10 years of Conservative gov who let this all happen so partisanship is silly. 

It is really all you need to know that Trudeau was sheepish and silent doing his press rounds the last week to avoid discussing this matter.  He reminded me of Bush telling stories to schoolchildren, dejected and sullen, knowing he was the buffoon in the spotlight and with no handler able to guide him through talking points.
