Secret Service Agents Rush to Protect Trump at Rally Apparently someone tried to breach the event's security barrier By Newser Editors and Wire Services Posted Mar 12, 2016 11:48 AM CST 412 comments Comments Donald Trump is briefly surrounded by Secret Service agents while on stage at a rally in Ohio on Saturday. (YouTube) (Newser) – A group of US Secret Service agents briefly formed a protective ring around Donald Trump at a rally Saturday in Ohio, the AP reports. The agents quickly left the stage and allowed Trump to continue his speech. A spokesperson for the Trump campaign says a man tried to breach the security buffer at the event. Four Secret Service agents then rushed onto the stage, as the audience chanted "Trump! Trump! Trump!" The agents quickly cleared. Video of the incident is here. Trump did not explain to the crowd what had happened, but said: "Thank you for the warning. I was ready for 'em, but it's much better if the cops do it, don't we agree?" Both the Secret Service and Trump campaign staff did not immediately respond to questions seeking comment. Trump was able to finish his speech and did so without apparent incident. A spokesperson says the man who tried to get past the security barrier was "removed rapidly and professionally." Trump called off a rally on Friday night in Chicago, after protesters filled the arena where he was scheduled to speak.
