MSNBC’s Richard Lui talks to Rochelle Ritchie, a political commentator and former House Democratic staffer. Ritchie says pipe bomb suspect Cesar Sayoc tweeted a threat to her following an appearance she made on television. Ritchie says Twitter initially determined that the threat did not violate Twitter rules. Twitter has since apologized.
