Former US President Donald Trump is suing Internet giants Facebook, Google and Twitter.

Trump, who was banned from major online platforms after storming the Capitol on January 6, announced on Wednesday that he would also go to court against the heads of the corporations - Mark Zuckerberg, Sundar Pichai and Jack Dorsey.

The 75-year-old Republican accuses the Internet companies of an attack on free speech and "illegal, unconstitutional censorship".

"There is no better evidence that Big Tech is out of control than the fact that they banned the incumbent US president," said Trump at his golf club in Bedminster, New Jersey.

“If you can do it to me, you can do it to anyone.

And that's exactly what they do. "

Trump also criticized the approach taken by internet companies in the fight against the spread of false claims about the corona pandemic.

He wanted to "hold Big Tech accountable," said Trump.

The ex-president plans to file the lawsuit in federal court in Florida, where he has lived most of the time since he left the White House in January.

Exile after storming the Capitol

Facebook, Twitter and the Google video platform Youtube had banned Trump after the storming of the Capitol by radical supporters of the then president.

They blamed Trump for the violence and saw a threat to further attacks.

Facebook said in early June that the Republican's account would be suspended until at least January 2023.

The ban could also be extended if a “public safety risk” persists.

Trump's banning from online platforms was a hard blow to the right-wing populist, who is openly toying with a 2024 presidential nomination.

He was able to reach tens of millions of followers directly via Twitter and Co.

Trump still refuses to admit his electoral defeat against Democrat Joe Biden on November 3, 2020.

He spreads the conspiracy theory that he actually won the election and was deprived of a second term through massive electoral fraud.

Trump repeated his completely unsubstantiated accusation of massive election fraud in front of supporters in the capital Washington on January 6, when Congress wanted to certify Biden's election victory.

Trump called on his audience to march to the Capitol and "fight the hell out of it".

Radical Trump supporters subsequently stormed the parliament building.

Five people were killed in the course of the violence, including a police officer and a Trump supporter who were shot by police.
