The Trump administration escalated its conflict with the tech industry on Wednesday, unveiling a website that asks people who think their viewpoints have been censored by social media platforms to share their stories — and their contact information.

President Trump, who seems to relish little more than a tweet storm, has repeatedly attacked Google, Facebook and Twitter for what he alleges is their bias against and suppression of conservative users. The companies have repeatedly denied those accusations.

The website published by the White House on Wednesday took those complaints to a new level, marrying the president’s online grievances to a data-gathering operation that could help him mobilize potential supporters during his re-election campaign.

The website’s opening page begins with a caps-lock proclamation that sounds like an applause line from one of the president’s raucous rallies: “SOCIAL MEDIA PLATFORMS should advance FREEDOM OF SPEECH.”
