Rep. Michael McCaul (R., Texas) said he didn't believe the Tsarnaev brothers acted truly alone in the Boston Marathon bombings in an interview on CNN Tuesday evening.
ERIN BURNETT: "Do you think they truly acted alone at this point?"
REP. MCCAUL: "I find that difficult to believe. I also find the idea that there wasn't any foreign connection difficult to believe. When you look how sophisticated these bombs were that they made. Most of the experts I talked to indicate that there had to have been some sort of trainer who trained them in this and some training ground that they went to to test these explosives. And whether that happened over in Chechen region or whether that happened in the Boston area, we don't know the answer to that, but it is the job of the FBI and Homeland Security to cast a wide net to make sure if there's anybody else involved with this horrible bombing, that we catch them."
