FBI director: U.S. facing greatest threat from terrorist groups since 9/11

FBI Director James Comey said Wednesday that the U.S. is at its greatest threat level from terrorist groups since 9/11.

Comey shared the information at a Senate FBI oversight hearing after Sen. Lindsey Graham questioned him on his agency's knowledge of terrorism.

"Do you agree with the following statement: There are more terrorist organizations with men, equipment and safe havens, along with desire to attack the American homeland, anytime since 9/11?" the South Carolina Republican asked.

"I agree," Comey said.
