Former U.S. President Donald Trump has asked an appeals court to revive his lawsuit against Twitter over his permanent suspension.

In a 96-page filing (pdf) submitted to the 9th U.S. Circuit Court of Appeals on Nov. 14, Trump’s lawyers allege government officials use social media platforms as “cat’s paws” to suppress opinions “that turn out to be correct or at least debatable,” such as Hunter Biden’s laptop, the COVID-19 pandemic, and 2020 election integrity.

The latest move as part of Trump’s battle against the social media giant came a day before the former president announced his third campaign for the White House in a Nov. 15 speech at his Mar-a-Lago resort in Florida.

The legal brief draws an analogy with Galileo Galilei, one of the fathers of modern science who believed the earth revolves around the sun, yet was convicted of heresy by the Catholic church.
