TV cameras caught the moment US president Donald Trump's face appeared to "drop" and he closed his eyes - seemingly falling asleep during a televised meeting. Trump seemed like he was struggling to stay awake, jerking suddenly when he heard his own name mentioned, but otherwise letting his chin fall closer to his chest.

Viewers quickly cottoned on to what was happening and turned to social media, with one tweeting: "Trump's face is drooping and his eyes are closed." Another echoed: "Briefly opens his eyes when he hears his name. My dog used to do that." While a third viewer posted: "Trump is unfit for office! The 25 Amendment ought to be utilised."

Someone else posted: "The way he jerks awake... scary."

Yet more X users tweeted: "His brain is running at a low idle," and "If Biden had looked like that in a cabinet meeting it would have been the lead story on Fox News for two weeks. They'd run with it as the top story every hour on the hour."

It comes after Trump was spotted with a discoloured hand and drooping face earlier this week. Standing behind Homeland Security head Markwayne Mullin in the Oval Office, his eyes seemed to close of their own accord while he was still standing.

Trump seemed to shake out his hand a few times, with some viewers suspecting make-up had been applied to conceal bruises his press secretary claims are from "shaking hands too much".

During the meeting, Mullin said at the podium: "It just seems surreal being in the Oval Office and having a president of the United States, er, speak so highly of me and recognise my family and know my family by name. It's humbling.

"I never take it for granted, but I've made this very clear. I don't care what colour your state is - if you're red or you're blue - at the end of the day, my job is to be secretary of Homeland and protect everybody the same."
