The Supreme Court voted to dismiss a lawsuit that claimed former President Trump violated the First Amendment by blocking some critics of his on the popular social media platform Twitter.

The Hill reports:

The lawsuit arose in 2017 after Trump’s social media account blocked seven people who had tweeted criticism of the president in comment threads linked to his @realDonaldTrump Twitter handle, which has since been banned on the platform.

Lower federal courts found that Trump’s Twitter account, where he often weighed in on official matters, constitutes a public forum and that blocking his detractors violated their constitutional free speech protections.

Justice Clarence Thomas on Monday wrote a 12-page opinion concurring with the court’s dismissal of the case.
