Not true.  Rona Ambroses is NOT THE PRIME MINISTER and will not become the Prime Minister.  She has no power to confer any benefits to those who lobby the government.  That is why there are different rules for the Prime Minister and Cabinet Ministers compared to ordinary MPs.  
What Trudeau did would have been perfectly fine for a Liberal backbencher and it would have been perfectly acceptable if Trudeau did this as an ordinary MP.
Why is it the liberal-left have to bend the facts for their own political purposes?
