A number of the country’s major brands are pushing to remove their ads from YouTube channels for far-right website Infowars and its founder Alex Jones, saying they were unaware the ads were placed there, CNN reported Saturday.

CNN reported that ads from several major companies and organizations — including Nike, 20th Century Fox, the Mormon Church, Expedia, Alibaba and the National Rifle Association — were being featured on Infowars's channels on the platform.

Many of the brands said they were unaware of the situation and canceled their ads on the channel after CNN reached out for comment. Several said they have reached out to YouTube about the situation.

Ad campaigns from YouTube don’t necessarily allow companies to know where their advertisements will show up but do allow organizations to use certain filters that keep their ads off certain content.

A number of the companies CNN spoke with said they are taking extra steps to ensure their ads do not show up on such content again.

YouTube reprimanded Jones earlier this week for posting a video that claimed the student activists from the Florida high school shooting last month that left 17 dead were actors.
