The president is preparing to nominate a new director of FBI today, just as two apparent cases of domestic terrorism, or at least violence, in this country are capturing the bureau’s attention: Letters containing threats against New York City Mayor Michael Bloomberg testing positive for the deadly poison ricin, and a Disneyland employee is in custody for allegedly setting off a dry ice bomb in Toontown.

CNN Counter Terrorist Analyst Fran Townsend weighs in on the threats and President Obama’s plans to nominate James Comey to replace Robert Mueller as FBI director.
