GRAND RAPIDS, Mich.- Former first daughter Barbara Bush spoke in Grand Rapids Thursday. She was among the featured speakers in Calvin College's January Series.

The annual series is a discussion about important issues of the current day.

The daughter of former president George W Bush, Barbara is also the co-founder of the non-profit Global Health Core. The nonprofit said it has fostered over 900 young leaders who believe health is a human right and who take an innovative approach to solving some of the world’s biggest global health challenges.  

Originally Jenna Bush Hager was scheduled to be the speaker but because of scheduling conflicts with NBC her sister Barbara stepped in. 

This month's series also features talks from NASA astronaut Leland Melvin and Rachel DenHollander, the whistleblower in the Larry Nassar sex abuse case.
