During GOP frontrunner Donald Trump’s campaign rally Saturday morning in Dayton, Ohio, it appears someone tried to grab the real estate mogul from behind while he was speaking on stage.

Several Secret Service officials jumped into action and surrounded Trump.

The crowd began chanting, “Trump!” and “U-S-A! U-S-A!”

“Thank you for the warning. I was ready for him, but it’s much easier if the cops do it, don’t we agree. What a great job!” Trump said.

Trump then said it’s payback time and time to make America great again.

The billionaire appeared to be uninjured and continued to speak.
