She sang for Obama - now she sings the anthem for Trump

As thousands of Donald Trump supporters were lining up for the Madison Square Garden rally on Sunday, singer Mary Millben was preparing backstage.

The BBC went behind-the-scenes with Millben before for her national anthem performance, where she spoke about her journey from White House intern, to singing for four presidents.
