The White House released photos showing Trump working in the Walter Reed National Military Medical Center, where he was undergoing Covid-19 treatment.

In the photos released by the White House on October 3, US President Donald Trump appears to be actively working with many of the documents on his desk.

On the same day, the US President's daughter Ivanka Trump tweeted a picture of her father still working hard.

"Nothing can stop me from working for the American people. Don't stop!", Ivanaka wrote, posting with a photo of the US President viewing a series of documents.

White House doctor Sean Conley, when updating Trump's health on the evening of October 3 (morning of October 4, Hanoi), said he still spends most of his time in the hospital working.

Trump was told that "is fine and has made significant progress since being diagnosed with nCoV".

In the latest Twitter video shot at Walter Reed, Trump says he is better and will "return soon".
