Kamala Harris' sister says she will call her 'Madam President' when she's elected, 'Until then...'

57-year-old Maya, a lawyer and a public policy advisor, said she is very proud to be part of Kamala Harris' presidential campaign and the feeling is extraordinary, electric. "I am just so proud to be able to be out there in these states encouraging people to knock on every door, call every voter, text their friends and family members between now and Election Day, to really have those personal conversations that help people learn who Kamala is, what she's fighting for, why they believe in her," Maya told People magazine.
