Cameras caught her coughing up what appears to be green mucus into the glass of water with images of the incident fuelling speculation across the web.

At the rally the 68-year-old was criticising her Republican opponent Donald Trump after his visit to Mexico and, after coughing, quipped: “Every time I think about Trump I get allergic.”

The website belonging to right-wing talk radio host Alex Jones published an article with the headline ‘Hillary caught on tape birthing alien life form’.
