Donald Trump publicly raised questions about Hillary Clinton’s health for the first time since the former secretary of state was forced on Sunday to leave a ceremony for the victims of 9/11.

Speaking in a well air-conditioned minor league basketball arena in Canton, Ohio, Trump made his most direct reference to Clinton’s recent diagnosis of pneumonia and her campaign saying she left the event in New York because she felt “overheated”.

“You think this is easy?” Trump asked. “In this beautiful room that’s 122 degrees. It is hot, and it is always hot when I perform because the crowds are so big. The rooms were not designed for this kind of crowd. I don’t know, folks. You think Hillary Clinton would be able to stand up here and do this for an hour? I don’t know.”

The Republican nominee later went on to add of his Democratic rival, “Now she’s lying in bed, getting better and we want her better, we want her back on the trail, right?”

Sounding like the classic unscripted Trump, the Republican presidential nominee often deviated from his teleprompters in a 40-minute speech that ranged from Clinton’s health to the water crisis in Flint, Michigan.
