Hillary Clinton may have stumbled and required assistance at a 9/11 memorial at Ground Zero Sunday morning, shown in a video posted by NBC News.
The Democratic presidential candidate was moved swiftly from the memorial in her campaign's van to her daughter Chelsea's New York apartment.
Clinton's campaign said she felt "overheated" before exiting the ceremony and is now "feeling much better."

Clinton herself greeted press outside of Chelsea's apartment (seen above).
"Secretary Clinton attended the September 11th Commemoration Ceremony for just an hour and thirty minutes this morning to pay her respects and greet some of the families of the fallen," said Clinton campaign spokesman Nick Merrill.
"During the ceremony, she felt overheated so departed to go to her daughter's apartment, and is feeling much better."
The ceremony was held in New York, keeping with an annual tradition that began in 2012. Both Clinton and Republican candidate Donald Trump attended the event along with other dignitaries.
Some conservatives have raised concerns over Clinton's health, some accusing her of hiding a serious illness.
Rudy Giuliani and other conservatives zeroed in on a coughing episode the Democratic candidate had at a Labor Day rally.
