Hackers briefly deface website for U.S. government library with pro-Iranian message

The homepage for the U.S. Federal Depository Library Program was briefly altered Saturday evening to show a pro-Iranian message and an image of bloodied Donald Trump being punched in the face, CBS News reports.

A line at the bottom read: "Hacked by Iran Cyber Security Group Hackers. This is only small part of Iran's cyber ability! We're always ready." 

The website was not accessible soon after the image appeared.
