Rep. King: Capitol bomb plot shows threat of 'lone wolf'

King is perhaps best known for holding a series of committee hearings on Islamic radicalization in America, which he has defended from critics as an important exploration of the threat posed by homegrown Muslim terrorists.

Ferdaus was arrested as part of an FBI sting operation in which he thought he was plotting an attack with members of al Qaeda who were actually undercover agents. King cautioned that while Ferdaus did not get very close to implementing his plan, he still represented a serious threat.

"[Ferdaus] didn't have the technology, he didn't have the equipment, but he had the brains, he had the plan, he had it all thought out. So really, he was 95 percent of the way there,” King told New York’s CBS 2.
