​The promotion of girls’ schooling has been the cornerstone of Obama’s charitable work since her husband Barack Obama left office in 2017 after two terms as US president.

“When you educate a girl you give them power and a voice and an opportunity to improve their lives and the lives of their family and the lives of their community,” Obama said at Can Giuoc high school in southern Long An province in the Mekong Delta.

Accompanied by Roberts and Jenna Bush Hager, daughter of former US president George W. Bush, Obama encouraged the girls to stay the course of schooling.
