After accusing him of doping before the first presidential debate, Donald Trump called his Democratic opponent for the White House Joe Biden "nuts" on Twitter.

For several days, the president has multiplied angry tweets while his delay in the polls remains significant. 

US President Donald Trump, lagging behind in the polls less than a month before the presidential election, on Wednesday called his Democratic opponent Joe Biden a "nut".

"He's been a nutcase for years and everyone knows it," the US president tweeted.

"The media is getting stuck with him and just trying to protect him," he added.

"Did you notice how all the negative things, like his very low IQ, are never mentioned again? Fake News!"

He's been a wacko for years, and everyone knows it.

The Lamestream Media is stuck with him and they are just now trying to clean up his act.

Notice how all of the bad things, like his very low IQ, are no longer reported?

Fake News!

"The Fake News media (...) only want to talk about Covid-19," he thundered Tuesday in a message written from the White House, which he found Monday evening after three days of hospitalization.

As the November 3 ballot approaches, polls are more worrying every day for the former New York businessman seeking a second term.
