A ChicagoÂ rally for Republican presidential candidate Donald Trump was postponed March 11 due to safety concerns.
The announcement from Trumpâ€™s campaign occurred after protesters crowdedÂ inside and outside of the arena, CNN reported.
There were reportedly at least five sections of the arena filled with protesters before Trump arrived, which prompted security concerns.
"Mr. Trump just arrived in Chicago, and after meeting with law enforcement, has determined that for the safety of all of the tens of thousands of people that have gathered in and around the arena, tonight's rally will be postponed to another date," the Trump campaign said in a statement. "Thank you very much for your attendance and please go in peace."

"I've never been more proud of my city," 25-year-old protester Maria Hernandez, who broke out into a dance when the rally was canceled.
Hernandez said she was there protesting Trump because of his immigration policiesÂ and racial divisions in the city.
"I'm protesting because I'm black and Mexican and I'm not sure where he wants to deport me to, but I deal with racism daily in Chicago and I've had enough," Hernandez said.
Supporters of Democratic presidential candidate Sen. Bernie Sanders of Vermont were also in attendance, chanting, â€śBernie,â€ť while holding up campaign signs for him.
"Protesters have won now," Marlin Patrick, 55, told CNN. "We just feel as if the protesters have taken over."
Trump responded to the violent protesters, telling CNNâ€™s Don LemonÂ that before this rally, there had not been â€śmuch of a problem.â€ť
"I don't have regrets," he said. "These were very, very bad protesters. These were bad dudes. They were rough, tough guys."
Trump also took to Twitter the morning of March 12 to respond to the actions of the protesters.
