WASHINGTON (AP) — Katie Couric has reversed course and taken responsibility for an edit that misrepresents the response of gun rights activists to a question she poses in a new documentary.

The segment in "Under the Gun" shows nearly 10 seconds of silence after Couric asks the activists how felons or terrorists could be prevented from purchasing a gun without background checks.

Audio of the exchange leaked last week reveals an almost immediate response to the question.

Couric writes in a message on the film's website that she regrets not raising her initial concerns about the segment "more vigorously."
