Donald Trump's campaign website was hacked on Wednesday afternoon with visitors instead seeing a cryptocurrency scam.
When users attempted to visit the 'About' page on donaldjtrump.com around midday, they were met with a message declaring: "This site was seized".
"The world has had enough of the fake news spreaded daily by president Donald Trump. it is time to allow the world to know the truth," the message said.
"We have evidence that completely discredits Mr Trump as a President. Proving his criminal involvement and cooperation with foreign actors manipulating the 2020 elections. The US citizens have no choice.
"Today is the day - the whole world can decide if they want to know that truth or not."
Further down in the message, the hackers ask for donations on cryptocurrency platform Monero in exchange for releasing the proof of the misconduct.
The hackers provided no evidence to back their statements.
Business Insider reported the website appeared to have been taken offline soon after the scam appeared. It is now back to normal.
Trump's presidential campaign said in a statement that they were aware the website was "defaced".
"We are working with law enforcement authorities to investigate the source of the attack," they said.
"There was no exposure to sensitive data because none of it is actually stored on the site. The website has been restored."
