WORCESTER, Mass. -- As police officers escorted a shouting protester out of the rally Donald Trump held in a converted ice hockey arena on Wednesday night, the crowd of 10,500 held up their cellphone cameras, booed and then chanted: "USA! USA! USA!"
"Isn't a Trump rally much more exciting than these other ones?" the presidential candidate marveled as he took in the scene. "And that kind of stuff only adds to the excitement, I tell you. Just incredible."
Trump's nontraditional run for the White House has resulted in a series of political rallies across the country where who-knows-what might happen. Here are nine things that happened during Trump's visit to Massachusetts:
1. During a press conference before the rally, reporters pressed Trump to explain why he continues to say President Obama plans to resettle 250,000 Syrian refugees in the United States even though the administration has only publicly committed to accepting 10,000. Trump said his larger number comes from a "pretty good source" and is likely accurate because he has correctly predicted a number of other foreign events, including the rise of Osama bin Laden.
"You watch," he said, "I'll be right."
2. Trump once again cursed as he described what he would do as president to Islamic State terrorists: "We've got to knock the s--- out of these people. We've got to do it. We've got to do it." The crowd once again began chanting: "USA! USA! USA!"
"And we can do it fast, and we can do it furious," Trump continued. "We can do it. We can do it well."
Trump mocked Obama for having said the Islamic State was contained just before Paris was attacked by terrorists.
"The only thing contained is us," Trump said. "We're contained because we have no leadership."
3. And Trump continued to warn his supporters that these terrorists could use the Internet as a weapon.
"They're using the Internet, and they're recruiting people," Trump said. "We've got to take back the Internet because they are taking people. They're literally brainwashing people. They're brainwashing our youth... We can't let that happen. We have innocent youth, and they are misguided."
4. Throughout the evening there were sporadic outbursts from protesters who were led away by police, often shouting and struggling as they went. As television journalists rushed to capture these interactions, Trump's campaign staff members tried to block several of them from doing so, refusing to let reporters leave a barricaded work area they called "the pen."
After CNN reporter Noah Gray left "the pen" to document a group of protesters who unveiled a sign reading "Migrant lives matter," Trump's campaign manager Corey Lewandowski turned to campaign spokeswoman Hope Hicks and said: "Hey: Tell Noah, get back in the pen or he's f------ blacklisted," according to a recording of the incident.
As Gray went into the crowd to film reaction to the sign, which had already been taken down, Lewandowski confronted him directly: "Inside the pen, or I will pull your credentials. Media goes in the pen." Lewandowski at first said the order was because of security, but then said: "I'm telling you. I'm telling you. Media stays in the pen."
5. One of the outburst came as Trump questioned the number of Americans on food stamps, a topic he rarely brings up on the campaign trail. As the man who caused it was led away, Trump said: "You know, it's amazing. I mentioned food stamps and that guy who is seriously overweight went crazy. He went crazy... That's an amazing sight."
6. After leaving rival Ben Carson alone for a few days, Trump resumed attacking the retired surgeon, pointing to a recent article in the New York Times that quoted a top adviser to Carson saying he had been unable to teach the candidate anything about the Middle East. Although Trump usually slams the newspaper for its coverage of his campaign, he urged the crowd to read its coverage of Carson.
"If you read the front page of the New York Times today, they said about Ben Carson that he's unable to understand foreign policy," Trump said. "You know, his people actually said this, that he's unable to comprehend or understand foreign policy. It was devastating."
7. Trump also went after rival Marco Rubio, mocking the senator from Florida for missing votes in Washington and once again calling him "a lightweight."
"Everyone says: 'Oh, Rubio, he's the next Reagan.' He's no Reagan -- that I can tell you," Trump said. The candidate then took another swipe at the younger politician: "I mean, my hair is better than his hair, that I can tell you."
8. And Trump went after Democrats, too, getting big cheers as he said Obama "has been a disaster for this country." The crowd also booed Secretary of State John Kerry of Massachusetts, prompting Trump to playfully put a hand to his ear. Trump called former Maryland governor Martin O'Malley, a Democrat running for president, "the other guy, he shouldn't even be on the stage." And Trump said he does not believe Democratic front-runner Hillary Clinton has "the strength or the stamina to be president."
"She's exhausted, folks," Trump said. "She's exhausted."
9. As he often does at rallies, Trump asked the crowd what should happen to Army Sgt. Bowe Bergdahl, who abandoned his post in Afghanistan in 2009, was held hostage and then rescued. Trump called Bergdahl "a dirty, rotten traitor."
"What do we do with Sgt. Bergdahl, 50 years ago?" Trump asked, calling on an older man sitting near the front who stood and shaped his hand like a gun. "That's right. Boom. Boom!... Boom, he's gone. He's gone!"
