Hillary Clinton's latest attack ad linking Donald Trump to the Ku Klux Klan and other white supremacist movements is "completely beyond the pale," a member of the Republican presidential nominee's evangelical advisory board said Thursday.

"Hillary Clinton and her campaign went to a disgusting new low today as they released a video tying the Trump Campaign with horrific racial images," Pastor Mark Burns said in a statement released by the Trump campaign.

The ad is the latest in a series of attack ads against Trump that his Democratic opponent has been airing in critical battleground states. The minute-long video features a robed KKK wizard explaining that "the reason a lot of Klan members like Donald Trump is because a lot of what he believes, we believe in," while footage of a Confederate flag waving in the wind plays onscreen.

Furthermore, the ad attacks Trump's newly hired campaign CEO, Steve Bannon, who previously served as chief executive of the conservative news site Breitbart. Critics have described Breitbart as a media outlet that peddles white supremacism and appeals to the "alt-right."

"This type of rhetoric and repulsive advertising is revolting and completely beyond the pale," Burns said. "I call on Hillary Clinton to disavow this video and her campaign for this sickening act that has no place in our world."

A spokesperson for the Clinton campaign could not be reached for comment.
