Has Trump’s first 100 days left America more divided?

President Trump has returned to Michigan, a state that helped propel him to the White House last November, to mark his 100th day in office with a speech to supporters. US correspondents Mark Stone, Martha Kelner and James Matthews ask what message he was trying to send to his base, and how it will have played with those who are less certain of his success in the last few months.  
 
And, as Mark Carney is named the new Prime Minister of Canada, is he dancing his way into a showdown with Trump?
