The White House on Thursday held a social media summit which gathered mostly conservative social media personalities.
Trump, a frequent Twitter user who has more than 60 million followers on that service, nonetheless renewed his complaint over "terrible bias" on social media, and vowed a response. "If I put it out on social media, it's like an explosion".
The "social media summit" went ahead without representatives from tech giants Facebook, Twitter and Google.
Facebook said it had not been invited while Twitter and Reddit declined to comment. He also talked about the need to protect free speech on online platforms and said that his administration is exploring solutions to this. Outside the gathering, Trump's aides appeared to line the hallways with poster boards calling attention to the tech industry's alleged tactics for suppressing conservatives' speech - along with at least one tweet from Trump himself calling him "the best" at using the service.
Trump has repeatedly claimed that firms such as Facebook, Google and Twitter - who were not invited to the summit - discriminate against him and his supporters, even though his own Twitter account has almost 62 million followers.
Sites like Twitter and YouTube, for example, allow actual terrorists, such as the Palestinian group Hamas, to maintain a large presence while blocking American patriots who question liberal dogma concerning Second Amendment rights by claiming it advocates violence. Free Speech is a bedrock of American life.
"Internet companies are not biased against any political ideology, and conservative voices in particular have used social media to great effect", said Michael Beckerman, president of the Internet Association, which includes Twitter, Facebook and Google.
Sen. Marsha Blackburn, a Republican from Tennessee, and Rep. Matt Gaetz, a Republican from Florida, were also invited to the summit, according to Politico. They were joined by organizations such as the Media Research Center, a conservative group that has called for the breakup of big tech companies, and PragerU, which produces right-leaning videos that it believes Google has censored - a matter the two sides are battling in court.
In a Twitter post fired off before the summit on Thursday, Trump said the "tremendous dishonesty, bias, discrimination and suppression practiced by certain companies" would be a key focus.
During the conference Trump praised the right-wing social media influencers. "We will not let them get away with it much longer". At the same time he seems to value social media as a counterbalance to the mainstream media, most of which he has been at war with for years.
