As the summit was about to begin on Thursday, Twitter went down for nearly an hour. The outage was due to an "internal configuration change" that was fixed by the time the President started addressing the summit.
Launching a fresh attack against Twitter, Trump complained his followers kept fluctuating on the platform and he is losing them fast, CBS News reported.
"People come up to me, saying 'Sir, we want to follow you; they don't let us on'," Trump told a gathering of conservatives and his far-right supporters.
Interestingly, no representative from Twitter, Facebook or Google was invited to be part of the summit.
"I have millions of people, so many people I wouldn't believe it, but I know that we've been blocked. People come up to me and they say, 'Sir, I can't get you. I can't follow you'," he added.
Twitter removed several fake accounts last year and in the process, Trump also lost nearly 3 lakh followers.
"The President said he's directing his administration to search for any regulatory or legislative action it can take to avoid censorship," the report mentioned.
Others present at the social media summit were Senator Josh Hawley, a Republican who favours stricter regulations for tech companies to avoid censorship.
Senator Marsha Blackburn and Republican Matt Gaetz were also in attendance who have accused Twitter of censoring tweets.
Right-wing provocateur James O'Keefe, the founder of Project Veritas, was also present.
In his last meeting with Twitter CEO Jack Dorsey, Trump reportedly questioned the former specifically on why he was losing followers the micro-blogging platform.
The White House recently launched a new tool for people to report if they have been wrongly censored, banned or suspended on Facebook and Twitter.
The tool comes in the wake of several Republicans slamming Facebook and Twitter for censoring conservative speech on both the platforms.
Trump in a March tweet accused Facebook, Google and Twitter of being "on the side of the Radical Left Democrats".
