"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," the message read.
The message also contained the claim that "Strictly classified information is exposed proving that the Trump gov is involved in the origin of the coronavirus".
The hackers did not provide any information to support their claims, but did provide two accounts for a cryptocurrency and invited users to place in funds in them to decide whether the information would be released.
Trump 2020 Communications Director Tim Murtaugh later released a statement on the hack, saying that no sensitive data had been compromised.
"Earlier this evening, the Trump campaign website was defaced and we are working with law enforcement authorities to investigate the source of the attack," Murtaugh wrote.
"There was no exposure to sensitive date because no of it is actually stored on the site. The website has been restored."
