Hilary Clinton finally spoke to reporters on Tuesday, defending her use of a private email account as a matter of “convenience.” We spoke with Politico’s Kyle Cheney and technology reporter Glenn Fleishman to find out more. Next up is Matthew Wall, business and technology reporter from the BBC, who chats with us about delivery drones in Africa. Finally, Marketplace’s Adriene Hill to talk about emotional learning technologies at SXSWedu, the education conference that’s underway in Austin.
