The White House asked YouTube on Tuesday to review an anti-Muslim film posted to the site that has been blamed for igniting the violent protests this week in the Middle East.

Tommy Vietor, spokesman for the National Security Council, said the White House has "reached out to YouTube to call the video to their attention and ask them to review whether it violates their terms of use."

However, the video remained on the site as of Friday afternoon, and it is posted many other places on the Internet.
