Having just come out of a closed-door briefing with the FBI, Senator Saxby Chambliss (R., Ga.), the intelligence-committee vice chairman, said that the motives of the suspected Boston Marathon bombers may not be as straightforward as originally thought. “As for the ‘why’ of it, that’s going to be a very complex and comprehensive investigation,” Chambliss told CNN’s Wolf Blitzer. “I’ll be honest, it is not clear even after the interview of the suspect in custody has been conducted. It’s still not clear exactly what did this.”
Dzhokhar Tsarnaev cited the U.S.’s involvement in Afghanistan and Iraq as one of his and his brother’s motivators in the bombing.
