Greta Van Susteren is not giving up on social media

Former cable news anchor Greta Van Susteren talks with Recode's Kara Swisher and SKDK's Hilary Rosen about her new book, "Everything You Need to Know about Social Media (Without Having to Call a Kid)." Van Susteren spent long stints hosting shows at CNN and Fox News and says she still doesn't know why her last TV employer, MSNBC, fired her after six months. In addition to the new book, she’s now an internet entrepreneur: Her first product is Sorry, an app for apologies. Van Susteren talks about all of that change, as well as what Silicon Valley companies should do about Russia's election meddling; why Donald Trump retweeted her recently and why that's not as big a deal as people think; and why, despite all the trolling and other nastiness, "social media is here to stay."
