-- Russia intercepted a communication between the mother of the accused Boston Marathon bombers and someone who may have been one of her sons "discussing jihad" in 2011, according to a U.S. official with knowledge of the investigation.
This source described the conversation as vague.
The Russians turned over the intercept to the FBI in the last few days, the official said.
This source was not aware of a reason for the delay and did not offer an opinion about whether it would have given the FBI enough reason to justify a closer look at Tamerlan Tsarnaev, the oldest of the two brothers.
U.S. Attorney General Eric Holder was asked abut the report while attending the White House Correspondents Dinner Saturday.
"That's an ongoing matter," Holder said. "I can't really comment on that."
