A theory has emerged that a video filmed by US President Donald Trump from hospital was edited to hide his symptoms of coronavirus from the public.
Mr Trump was flown to hospital after testing positive to Covid-19 late last week.
Mr Trump has maintained he’s OK.
In a four-minute video posted on Twitter on Saturday (local time) from his suite at the Walter Reed National Military Medical Centre, a tired-looking Mr Trump said he was feeling "much better."
"Over the next period of a few days, I guess that's the real test, so we'll be seeing what happens over those next couple of days," he said, seated in front of an American flag while wearing a jacket and open-necked shirt.
However, there have been some suggestions from viewers that the video has been edited.
At one point, Mr Trump says “if you look at the therapeutics - which I’m taking right now, some of them”. The US President appears to pause briefly and either hiccup or cough mid-sentence.
But viewers have speculated this part was cut out.
One Twitter user suggested the Trump coughed but it was removed using Adobe Premiere Pro’s morph cut feature between the words “therapeutics” and “which”.
Another man added there is “clearly a cut” in the video.
“Hard to imagine any rationale other than persuading the American public that he is healthier than he actually is,” he tweeted.
However, other people suggested he’s spasming as a result of the virus and the video hasn’t been edited.
Others have suggested it was filmed before he was hospitalised but photos released by the White House seem to refute this claim with photos of the president working at Walter Reed with the same background as the video.
Mr Trump's vitals over the last 24 hours were “very concerning” and the next 48 hours will be “critical” in terms of his care, White House Chief of Staff Mark Meadows told reporters on Saturday.
“We're still not on a clear path to a full recovery,” he said.
Mr Meadows altered his tone hours later, telling Reuters that Mr Trump was doing "very well" and that "doctors are very pleased with his vital signs."
A Trump adviser, who spoke on condition of anonymity, said the president was not happy to learn of Meadows' initial remarks.
Another source said Trump was given supplemental oxygen before he went to hospital.
The decision to hospitalise Mr Trump came after he had experienced difficulty breathing and his oxygen level dropped, according to the source.
White House doctor Sean Conley told reporters outside the hospital on Saturday that Mr Trump had not had trouble breathing, and was not given oxygen at Walter Reed.
"The team and I are extremely happy with the progress the president has made," Dr Conley said.
