This is a powerful and emotional day for the witnesses and for this committee. It is a time to remember the anniversary of the Boston Marathon bombings, and it is a time to remember the victims. This committee, through its oversight responsibilities, conducted a thorough investigation into what happened and what went wrong. We found that several flags and warnings were missed. We found that Tamerlan Tsarnaev was on the radar of the FBI and somehow dropped off. We found that Mr. Tsarnaev traveled to Dagestan, known for its Chechen terrorists, precisely what the Russian letter warned our intelligence community and FBI about. He came back even more radicalized. We also found that Customs, FBI, and the intelligence community somehow missed it. There are still unanswered questions about the history of the Tsarnaev brothers, the alleged Boston Marathon bombers, and we owe it to the people of Boston and the rest of America to make sure that the appropriate officials do a thorough review of that situation.
