National Security Adviser Jim Jones apologized today for a controversial joke he made about a Jewish merchant.

Appearing before the Washington Institute for Near East Policy, a pro-Israel think tank, Jones opened his speech with a joke about a Jewish merchant who tricks a Taliban fighter. (video below).

The quip was received well by the audience, but has since raised eyebrows for seeming to perpetuate stereotypes about Jews.

Jones said today he should not have told the joke.

“I wish that I had not made this off the cuff joke at the top of my remarks, and I apologize to anyone who was offended by it," Jones said in a statement. "It also distracted from the larger message I carried that day: that the United States commitment to Israel’s security is sacrosanct."
