Donald Trump appeared to accidentally retweet a post describing him as a 'fascist', before swiftly deleting the retweet.
The tweet by Mike Holden was sent in response to a story from the US Fox & Friends news programme, which was also retweeted by the US president.
The story reported that President Trump is 'seriously considering' a pardon for ex-sheriff Joe Arpaio, who the New York Times reports was convicted last month for "defying a court order to stop detaining suspected undocumented immigrants".
The story prompted a response from Mr Holden, who only had around 700 followers before his newfound Internet fame.
He's a fascist, so not unusual.

Mr Holden appeared to enjoy the attention from the unexpected retweet from @realDonaldTrump, updating his profile to say: "Officially Endorsed by the President of the United States. I wish that were a good thing."
Speaking to the Washington Post, Mr Holden said he is a 53-year-old living near Manchester in England.
Explaining his use of the word 'fascist', Mr Holden told the US newspaper: "It’s a strong term to use, but I wouldn’t apologise for it.
"Why he retweeted it is beyond me, but maybe he got a taste of his own medicine."
President Trump also found himself receiving online attention for another retweet (again swiftly deleted), featuring a cartoon showing a person with a CNN logo for a head being hit by a train.
A number of Twitter users highlighted that the retweet came only days after the death of Heather Heyer in Charlottesville, who was hit by a car while she was protesting against a white nationalist rally in the Virginia city.

Yesterday, President Trump refused to answer questions from CNN reporter Jim Acosta about his widely criticised initial response to the Charlottesville violence, and instead again hit out at the network as 'fake news'.
