Minutes later, he reappeared to cheers, declaring: "Nobody said it was going to be easy for us, but we will never be stopped, never ever be stopped. I want to thank the Secret Service. These guys are fantastic. They don't get enough credit. They don't get enough credit. They are amazing people."
There were signs of a fracas in the audience as the agents led Trump away, but once a suspect was in custody Trump returned to resume his stump speech.
Television footage showed a suspect pinioned on the ground by officers and searched, before he was led away by local law enforcement, including an armed response team in tactical dress with rifles. The US Secret Service confirmed there was never a gun.
The Guardian says that man who was feared to have a gun claims to be a Republican supporter opposed to Trump. He held a sign that said "Republicans against Trump".
Initially, his sign elicited boos, "And then all of a sudden people next to me are starting to get violent; they're grabbing at my arm, trying to rip the sign out of my hand," he said. While he said he couldn't be positive, he it "it looked like Trump was pointing at him.

Eric Trump, Donald's son, retweeted a message saying "Hillary ran away from rain today. Trump is back onstage minutes after an assassination attempt". He appears to have deleted the retweet from his account. It was pointed out on CNN that there was no assassination attempt.
Trump campaign manager, Kellyanne Conway, attributed the speading of misinformation to Eric being "rattled", after seeing what appeared to be an attempt on his father's life. She herself had reiterated claims that the protester was a"democratic plant or operative".
Critics are scared about the Trump campaign's reaction to a peaceful protest:
A politician who blatantly lies by describing a peaceful protest as an "assasination attempt" will do the same to his opponents once elected
