Clad in dark formal suit with temperature around 28C and 46 percent humidity, presidential candidate Hillary Clinton departed from the 9/11 memorial event in downtown Manhattan after feeling "overheated."

According to one of his campaign spokesmen, Nick Merril, the Democratic contender attended the "September 11th Commemoration Ceremony for just an hour and 30 minutes."

On Twitter, Merril said:

Joining the thousands of New Yorkers in paying respect to the fallen of the September 11 terrorist attack, Secretary Clinton was rushed to her vehicle and brought to the apartment of her daughter Chelsea.

Meanwhile, Republican presidential candidate Donald Trump also attended the ceremony.
