WASHINGTON (CNN) — On the same day ISIS front man Jihadi John is unmasked as Mohammed Emwazi of London — outgoing U.S. Attorney General Eric Holder vowed, “Anyone involved in the killing of American citizens will be held accountable. It doesn’t matter where you are, we will find you. We will hunt you down and we will hold you accountable.”
Holder would not confirm the suspected terrorist’s identity or reveal whether the U.S. government knows where Emwazi is — but he insisted America will not relent in bringing to justice the man seen in ISIS videos showing the beheadings of U.S. hostages and other Westerners.
“Whether it’s through the use of our military or the use of our law enforcement capacity, if you harm Americans it is the sworn duty of every person in the executive branch to find you and hold you accountable, and we will do that,” he said.
Holder, who will be retiring in the coming weeks, sat down for a 10-minute exit interview with CNN on Thursday.
CNN Justice Correspondent Pamela Brown pressed Holder asking, “Do you think we would go as far as to send U.S. troops to find Jihadi John and hunt him down?”
“I wouldn’t put anything off the table,” Holder said.
The attorney general also admitted the threat of a lone wolf attack inside the United States keeps him awake at night.
In light of a recent video urging attacks on shopping malls in the U.S. and other countries, Holder said malls should increase security to help prevent such attacks.
The video released over the weekend by extremist group Al-Shabaab specifically named the Mall of America in Minnesota and appeared to be designed to inspire terrorist attacks similar to the one on the Westgate Mall in Nairobi, Kenya, two years ago in which 60 people were killed after a four-day standoff.
“I certainly think we have to step up our sensitivities to what goes on in these commercial enterprises,” Holder said. “And, I think it would be the responsible thing for operators of these malls to increase their capabilities when it comes to keeping people safe who are just going about their everyday lives.”
Holder stopped short of saying malls should employ body scanners like those used at airports, though.
“There are a variety of ways you can increase security, increase the presence of people who are responsible for security, cameras that you can use, a variety of techniques that I think can be employed that won’t negatively impact the experience of fun that we have of going to a mall while at the same time enhancing the security of people who go there, people like myself, people like my kids,” he said.
