Donald Trump has accused Twitter of restricting the visibility of prominent Republican politicians on its platform, without providing evidence, and the US President promised to investigate.
The practice involves limiting the visibility of a user in search results, specifically in the auto-populated dropdown search box on Twitter.
And the the Republican president wrote in a Twitter post: "Twitter 'SHADOW BANNING' prominent Republicans. Not good. We will look into this discriminatory and illegal practice at once!"
Trump's comments followed a Vice news report on Wednesday that Republican National Committee Chairwoman Ronna McDaniel and other Republicans including Donald Trump Jr's spokesman were being "shadow banned."
"The notion that social media companies would suppress certain political points of view should concern every American. Twitter owes the public answers to what's really going on," McDaniel wrote on Twitter.
Twitter did not have a comment on Trump's tweet but a spokesperson said the company does not "shadow ban."
"We are aware that some accounts are not automatically populating in our search box, and we're shipping a change to address this," the spokesperson said in a statement."
Twitter said the technology used is based on user behaviour not political views.
