Social media is an integral tool used by the Islamic State in Iraq and Syria to recruit fighters and disseminate propaganda worldwide. In fact, thousands of ISIS-controlled Twitter accounts post more than a million Tweets every day. In response, the federal government has launched an initiative to counter violent extremism among potential homegrown terrorists. Part of the effort enlists college students to develop an online campaign and social media strategy against ISIS propaganda. On Saturday, NewsHour's Christopher Booker reports on a competition sponsored by the U.S. State Department and Facebook that involves students from West Point Military Academy, New York University, and 40 other schools trying to discourage extremism.
