In order to get the meaning of the line relating to the white house, you have to understand the Canadian way of apologizing.

Canadians apologize to others not only to accept blame, but also to express sorrow.

Saying things like "I'm sorry your dog got hit by a car but your new one is nice too" does not indicate that the person making the statement actually drove the car. It's an expression of sorrow.

So, the writers of "22 minutes" or whoever created the "Canadian Apology" are mutually expressing sorrow and taking blame.
