Federal investigators are in Russia this morning talking to the parents of the accused Boston bombers.
There are several agencies involved and some here on Capitol Hill complain those agencies aren't sharing information.
An interview with the parents of the bombing suspects resumed early this morning in Russia.
Tuesday's meeting was described as friendly. It lasted several hours. The mother was told she can see her son Dzohkar who is now in fair condition at a Boston hospital. "When she became increasingly devout, Tamerlan, the older brother gravitated towards her. And it's a very interesting question about what influence she had over Tamerlan," said NBC News Terrorism Analyst, Roger Cressey.
Investigators also want to talk with the wife of the older bombing suspect. She's with family in Rhode Island. So far, they've only been able to talk with her attorney.
Lawmakers got another classified briefing. "The main question is the FBI's investigation going back to 2011 and why it was not followed up since then," said Rep. Peter King, (R) New York.
"That's what a thorough investigation will produce, answers to all the questions we have about these two individuals, their activities, their travel, their associations, what motivated them," said White House Press Secretary, Jay Carney.
"I'm very concerned that there still seems to be serious problems with sharing information," said Senator Susan Collins, (R) Maine.
On Capitol Hill, the secretary of homeland security explained why Tamerlan Tsarnaev's trip to Russia raised no red flags. "The FBI, uh, text alert on him at that point was more than a year old and had expired," said Homeland Security Secretary, Janet Napolitano.
Today, the focus is back in Boston -- where Vice President and Mrs. Biden attend a memorial for Sean Collier, the 26-year-old M.I.T. officer slain during that city's week of terror.
