A former USA president, Donald Trump, launched a new communications platform, named "From the Desk of Donald J. Trump", with a video posted on the platform on Tuesday, describing it as "a place to speak freely and safely". "We'll have additional information coming on that front in the very near future".
The feed is a running list of undated statements from the former president, with the most recent attacking House Republican Conference Chairwoman Rep. Liz Cheney (R-Wyo.) - who continues to criticize Trump over the January 6 storming of the Capitol.
Some said Facebook should have banned Trump long ago, while others called the ban "censorship" and argued it was a display of unaccountable corporate power over political speech.
On Wednesday, his fate on Facebook, the biggest social platform around, will be decided. It also allows leaders to interact with other public figures and engage in "foreign policy saber-rattling".
Visitors to the page are unable to comment on the posts, but there are options for sharing the messages to Facebook or Twitter.
Twitter, where Mr Trump had 88 million followers, has banned him permanently.
"This is just a one-way communication", one source familiar with Trump's new messaging center told Fox.

Alphabet Inc's YouTube has said it will restore Trump's channel when it decides the risk of violence has decreased.
