Presidential candidate Hillary Clinton suffered another coughing fit on the campaign trail.
The 68-year-old Democratic frontrunner was seized with coughing fits while speaking in Harlem, NY on Tuesday.
Clinton struggled to speak in between gulps of water. As she gasped for air, the crowd clapped and chanted "Hillary! Hillary! Hillary!"
"What's wrong with her?" some members of the audience murmured.
When she finally regained her composure Clinton spoke with a raspy, trembling voice.
Clinton quickly finished her speech about helping black Americans to overcome “seen and unseen” barriers to opportunity. She walked off the stage, still coughing.
Mrs. Clinton suffered coughing fits last month during campaign stop in West Des Moines, Iowa, and last year during the Benghazi hearings.
Her medical history includes blood clots in her legs and a brain aneurysm in 2013.
