The donation, it said, was also given in honor of John Lewis, the congressman and civil rights icon who died last year. As part of the gift, the foundation said Bezos has asked for the plaza at the Obama Presidential Center, under construction on Chicago’s South Side, to be named after Lewis. Valerie Jarrett, a former senior adviser to Obama who serves as the foundation’s CEO, said in a statement that the foundation was “thrilled” by that idea.
