Washington: U.S. President Donald Trump alleged that the social media company, Twitter Inc on Thursday of had restricted the visibility of prominent Republicans present on its platform. The allegations he made were without providing any kind of evidence, and he promised to get the matter investigated.

“Twitter ‘SHADOW BANNING’ prominent Republicans. Not good. We will look into this discriminatory and illegal practice at once!” the Republican president wrote in a Twitter post.

The practice is based on limiting the visibility of a user in search results on the platform, specifically in the auto-populated dropdown search box on Twitter.

Trump made his comments after a Vice news report on Wednesday that Republican National Committee Chairwoman Ronna McDaniel and several 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 any comment to say 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 behavior, not political views.

Twitter made a policy change on July 12 this year to increase the service’s credibility factor and reduce suspected fraud. The change in policy cost its 100 most popular users at least 2 percent of their followers, on average, according to social media data firm Keyhole.

The alternation cost former President of US Barack Obama 2 million followers by the morning after the change and singers Katy Perry and Justin Bieber each lost at least 3 million, The Washington Post reported, citing analytics company Twitter Counter.

The report went into details about Trump’s account on the platform and said that he lost more than 200,000 of its 53 million followers.

Twitter shares in the share market, already proved lower in premarket trading after Facebook Inc’s disappointing earnings late Wednesday damped enthusiasm for technology and social media stocks, dipped down a bit further and volume rose slightly after Trump’s tweet at 7:46 a.m. The stock was last down 3.2 percent.

Trump is considered to be the Twitter-savvy person for posting tweets now and then over important and not-so-important issues. He has a large base of followers on the social media platform, Twitter.
