Members of the Senate Intelligence Committee spent more than two hours grilling FBI Deputy Director Sean Joyce on Tuesday afternoon on details of the Boston Marathon bombings.

Intelligence Committee Chairman Dianne Feinstein (D-Calif.) emerged from the meeting to say that federal investigators face "a long, arduous task" in reconstructing the events that led to the bombing. She declined to comment on specific concerns raised or information shared, but said she believes that the bombing incident "will be completely solved."

The panel's ranking Republican, Saxby Chambliss (Ga.), said the surviving suspect, Dzhokhar Tsarnaev, has provided "minimal information" to investigators. Chambliss suggested that miscommunications at counter-terrorism agencies that failed to thwart the Sept. 11, 2001,  attacks may have reemerged.
