Hillary Clinton had to exit the 9/11 anniversary ceremony early because the Democratic presidential candidate was “overheated,” her campaign said in a statement on Sunday.

At the event at ground zero in lower Manhattan, Clinton attended “to pay her respects and greet some of the families of the fallen,” said spokesman Nick Merrill. However, she left the ceremony after 90 minutes.

“During the ceremony, she felt overheated so departed to go to her daughter’s apartment, and is feeling much better,” Merrill said.

According to the Associated Press, Clinton left her daughter, Chelsea’s, nearby apartment shortly before noon and told reporters “I’m feeling great.” “It’s a beautiful day in New York,” she added. She posed with a photo with a young girl before heading into her motorcade.

A senior law enforcement official, speaking to the AP on the condition of anonymity, said Clinton was observed “fainting” in the departures area at the event, which also saw Donald Trump attend. The news comes as Trump supporters continue to argue that the 68-year-old candidate is physically unfit to take to the Oval Office.

To combat the health rumors, the Clinton campaign previously released a statement from her personal physician saying she’s in “excellent health.” In an appearance on “Jimmy Kimmel Live” last month, Clinton said the health rumors are part of a “wacky strategy” against her.

New York’s Democratic senators Kirsten Gillibrand and Chuck Schumer also attended the 9/11 event.
