While O'Reilly hasn't been a fan of Jay Z or Beyonce in the past, he suggested that the video leak went too far.
"I wish [videos like this] were not leaked to the public," said O'Reilly. "I don't see what the public good is other than titillation. I feel terrible for Jay Z and Beyonce and even Solange, who was so angry. I don't think they should be held up to ridicule."
The 64-year-old TV personality went on to praise Jay Z for the way in which he handled the situation, saying, "[Jay Z] looks like he's restrained on the video and that's a mature situation when you're under attack by anyone."
The Standard Hotel is now investigating how the footage got leaked.
"We are shocked and disappointed that there was a clear breach of our security system and the confidentiality that we count on providing our guests," The Standard Hotel said in a statement to ET. "We are investigating with the utmost urgency the circumstances surrounding the situation and, as is our customary practice, will discipline and prosecute the individuals involved to our fullest capacity."
