(CNSNews.com) - The National Park Service reportedly plans to unveil a "more balanced" version of a video that's been shown since 1995 as part of an exhibit at the Lincoln Memorial.

The Washington Post's Al Kamen, in his column, "In the Loop," credits the change to "intense conservative criticism." The column cites CNSNews.com's reporting on the video with jumpstarting the revision effort. "Some less than positive mail started flowing to the Park Service," Kamen said.

The video features portions of President Abraham Lincoln's speeches played over a video montage showing protests in favor of abortion rights, homosexual rights, gun control, and against the Vietnam War.

As CNSNews.com reported, the video appeared to imply that Lincoln would have supported these causes.

According to Kamen, National Park Service spokesman Dave Barna said, "it was unclear how much, or whether, the original would be edited."

However, Barna said it could be redone to feature all presidents who have visited the memorial since 1922, or, he said, some conservative events could be added.

Kamen said the problem with that is that "there haven't been many conservative demonstrations at the memorial, which has been a focal point for liberals for many years."

According to Kamen, Barna said the plan is to add footage of the Christian "Promise Keepers" rally in 1997 and a Desert Storm march after the first Persian Gulf War. But, Kamen points out neither of those events took place at the memorial. The events took place on the Mall.

The completion of the new video is expected in mid-December.
