After gun rights activists accused Couric and director Stephanie Soechtig of "selective editing" in the project, the veteran broadcast journalist issued a statement on Monday night (30May16) in which she apologised for any misrepresentation.

The Epix Original documentary which premiered at Sundance Film Festival earlier this year (16), and was aired on channel Epix on 14 May (16), focuses on the effects of gun violence in the United States.

Controversy flared after members of the pro-gun Virginia Citizens Defense League (VCDL), who were interviewed for the film took issue with a section where Couric asks the members about background checks on gun ownership.

In the version screened, a long pause followed, which implied the members were stuck for an answer, but the transcript shows they responded right away.

In her statement which was posted on the Under the Gun website, Couric, 59, admitted the film had been edited for "dramatic effect", and that it did not "accurately represent" the response from members of the VCDL.

"When I screened an early version of the film with the director, Stephanie Soechtig, I questioned her and the editor about the pause and was told that a 'beat' was added for, as she described it, 'dramatic effect,' to give the audience a moment to consider the question," she explained.

"When VCDL members recently pointed out that they had in fact immediately answered this question, I went back and reviewed it and agree that those eight seconds do not accurately represent their response."

Couric, who narrates Under the Gun and also executive produced the project, tweeted a link to her statement on the issue as well as posting the full transcript of the interview after speaking to award-winning writer, producer, and documentary film director Soechtig about the editing process.

She added: "I regret that those eight seconds were misleading and that I did not raise my initial concerns more vigorously."
