US President Donald Trump has attacked Robert Mueller’s investigation into Russian interference in the 2016 US presidential election, calling it a “total mess” and “absolutely nuts”.
He tweeted on Thursday that investigators were “threatening” people to provide “the answers they want”.
“They are screaming and shouting at people,” Mr Trump wrote, adding that no collusion between his election campaign and Russia had been found.
He says the inquiry is a “witch hunt”.
The US president has previously said the special counsel investigation led by Mr Mueller, who is a highly regarded former head of the FBI and a Republican, was unfair and dominated by “hardened Democrats”.
In Mr Trump’s latest tweets, he describes Mr Mueller as “conflicted” and says that those involved in the long-running probe “are a disgrace to our nation”.
The president later tweeted that Mr Mueller and “his gang of Democrat thugs” were destroying people, and blamed social media tech giants for unfavourable coverage towards his administration and the Republicans.
“Check out how biased Facebook, Google and Twitter are in favour of the Democrats,” he wrote.
It is unclear what was behind his latest comments and Mr Trump did not provide any evidence for his claims.
