BOISE (KTVB/AP) -- A Boise filmmaker says one of Gov. C.L. "Butch" Otter's campaign advertisements uses footage he filmed of gay rights protests during the 2014 Idaho Legislature.

The Lewiston Tribune reports that Otter's ad uses leftover footage that didn't make it into the feature length movie highlighting the multiple demonstrations that took place at the Idaho Statehouse urging lawmakers to add protections for gays, lesbians, bisexuals and transgender individuals.

Michael Gough says he put the footage cut from the documentary on his website to sell.

Gough added that Otter's campaign paid $75 to use his five-second shot of the interior view of the Idaho Capitol dome.

Otter has publicly opposed gay marriage in Idaho and has continued to fight the federal courts despite the ban being overturned last week.
