Trump last year filed lawsuits against Twitter, Facebook and Alphabet's (GOOGL.O) Google after they banned him from their platforms following the Jan. 6 riot.
U.S. District Judge James Donato in San Francisco in May dismissed Trump's lawsuit against Twitter, rejecting the former president's claim that the ban violated his First Amendment freedom of speech.
Twitter said at the time it permanently removed Trump's account as his tweets had violated the platform's policy barring "glorification of violence."
