The chairman of the House Homeland Security Committee said Sunday he believes the Boston bombing suspects received some sort of training before the deadly marathon attack.
"I think given the level of sophistication of this device, the fact that the pressure cooker is a signature device that goes back to Pakistan, Afghanistan, leads me to believe...that there was a trainer," Congressman Michael McCaul (R-Texas) said on "Fox News Sunday."
"The question is where is that trainer, or trainers? Are they overseas in the Chechen region or are they in the United States?" McCaul continued. "In my conversations with the FBI that's the big question. They've casted a wide net both overseas and in the United States to find out where this person is, but I think the experts all agree there is someone who trained these two individuals."
Nineteen-year-old Dzhokhar Tsarnaev was moved Saturday to a federal medical detention center about 40 miles outside Boston, the Associated Press reported, one week after he was captured by authorities. His older brother Tamerlan Tsarnaev was killed after a gun battle with police.
