Facebook revealed Thursday that it is looking into the deletion of a post by former Alaska Gov. Sarah Palin in which she criticized plans for a mosque near Ground Zero in New York City, CNN reported.

Facebook was investigating the incident “to determine why and how the content in question was removed," spokesman Andrew Noyes said in a statement.

Palin posted a new version of the Facebook note Thursday morning, responding to New York City Mayor Michael Bloomberg, who commented on earlier remarks by Palin about the planned mosque, according to the story.

“To build a mosque at Ground Zero is a stab in the heart of the families of the innocent victims of those horrific attacks," Palin says in the post.

Facebook users are able to report violations of the site’s terms of service, including content that users believe is racist or hate speech, the story says.

Palin’s reposted note also states: "The original post of this statement (on July 20, 2010) was somehow unintentionally deleted by mistake or technical glitch."
