A new report by Congress is raising questions about whether the Boston Marathon bombing could have been prevented. Rep. Michael McCaul (R-TX), chairman of the House Homeland Security Committee, joined Bill Hemmer this morning to go over the findings.

McCaul believes the attack could have been stopped if the FBI had taken Tamerlan Tsarnaev more seriously as a potential threat, especially after he traveled to Russia for five months in 2012. After traveling to Russia as part of the Congressional investigation, McCaul believes Tsarnaev was radicalized by militants in the Dagestan region.

"A lot of warning signs were out there. A lot of flags went up. He was on the radar screen of the FBI and fell off the radar. I believe that potentially this could have been stopped," said McCaul, highlighting the fact that Russia warned the U.S. about Tsarnaev's possible links to militants.
