Twitter sued by U.S. widow for giving voice to Islamic State

Twitter Inc is being sued by the widow of an American killed in Jordan who accuses the social media company of giving a voice to Islamic State, adding to the pressure to crack down on online propaganda linked to terrorism. Tamara Fields, a Florida woman whose husband Lloyd died in the Nov. 9 attack on the police training center in Amman, said Twitter knowingly let the militant Islamist group use its network to spread propaganda, raise money and attract recruits.
