On Donald Trump's repeated claim that President Obama is the "founder of ISIS": Trump walked the statement back on Twitter this morning, saying he was being sarcastic. But it gives our history guy, Chris Woolf, a chance to remind us all of the real origins of ISIS. Plus, US fans aren't the only ones celebrating Simone Biles' epic Olympic gymnastics performances. They're also celebrating in Belize, where Biles is a dual citizen. And, New York City plays host this weekend to a rice-off, specifically a "Jollof Rice-Off!" Many countries in West Africa lay claim to the spicy, glistening grain dish Jollof. Chefs will gather at the African Food Festival to prove who makes it best.
