"Public service is a bright, sharp, hot spotlight," said Mrs Obama, who spent eight years in the White House while her husband, Barack Obama, was US president."And most people don't understand it, and nor should they. The thing that I always keep in mind is that none of this is about us in public service, it's about the people we serve."....Mrs Obama, 57, was asked about the moment Meghan told Oprah she had "experienced racism"."As I said before, race isn't a new construct in this world for people of colour, and so it wasn't a complete surprise to hear her feelings and to have them articulated," Mrs Obama replied.
