President Donald Trump on Tuesday posted a video on Twitter that appeared to be part of his 2020 reelection campaign. In less than three hours, it had already amassed over 1 million views, but by late Tuesday night, the video was no longer available.

BuzzFeed News has learned that Warner Bros. Pictures filed a copyright infringement complaint to have the video taken down because it uses part of the score from the studio's 2012 film The Dark Knight Rises.

In a statement Tuesday night, Warner Bros. confirmed it was taking action over the video.

"The use of Warner Bros.’ score from The Dark Knight Rises in the campaign video was unauthorized," a spokesperson said. "We are working through the appropriate legal channels to have it removed.”

By late Tuesday night, the video in Trump's tweet had been replaced by a message that it was no longer available "in response to a report by the copyright owner."
