King suggested Saturday that the FBI may not have vetted Tamerlan Tsarnaev thoroughly enough. The 26-year-old Chechen is suspected of perpetrating the attack, along with his younger brother. According to multiple reports, Russian officials warned the FBI of Tamerlan's possible terrorist ties.
"I'm not at all convinced that the FBI couldn't have missed something or didn't drop the ball," he continued.
The California lawmaker said that appropriate congressional committees would be questioning both the FBI's procedures and its adherence to them as they examined the Boston bombings.
"I want to see what kind of request and intelligence we received from the Russian government or others," Schiff said. "All of that ought to be provided to the congressional committees and it will. I guarantee you there's no way that we are going to rest until we see all of the information at our disposal so that we can make conclusions about, you know, what can be done to improve things in the future."
But Schiff said he disagreed with Republican lawmakers that have suggested that Dzhokhar Tsarnaev, who was captured Friday night after a daylong manhunt, should be treated as an enemy combatant.
"I don't think there's a constitutional legal basis to treat him as an enemy combatant," Schiff said. "We're talking about an American citizen, arrested on American soil with as yet no clear connection. So I don't see how we can do this constitutionally."
Schiff added that he believed "we can accomplish a lot of the information gathering that we need under a constitutional structure without establishing a precedent where we're gonna treat Americans like enemy combatants and throw them in a brig without having legal or constitutional basis to do so."
