That early escort, for what other attendees described as rude behavior, set the tone for one of the most protest-riddled campaign rallies held yet by Donald J. Trump. More than two dozen people were escorted from the event at Dorton Arena here for various forms of protest, causing the candidate to stop his stump speech about 10 times until the shouts and boos subsided.

“Be very nice to the protester,” Mr. Trump said after he was interrupted just five minutes into his speech. He then paused to discuss the demonstrators, making sure to criticize the way the news media covers the protests at his events.

“When I’m rough and I say ‘Get them out of the room,’ they say, ‘Oh, that’s terrible,’ ” Mr. Trump said, mimicking media reports. “Then when I’m nice, I say, ‘Be very careful, be very gentle, don’t hurt the protester,’ then they say, ‘He was very weak tonight.’ So you can’t win. So I’ll try and cut it right down the middle. Make sure that young lady is in beautiful shape, and if she’d like us to let her back in, do we invite her back in? I don’t know.”
