Twitter has since Trump took office in 2016 flagged the president's tweets over concerns about their content. However, the company temporarily suspended his official presidential account after the supporters on Wednesday stormed the U.S. Capitol Building. Twitter permanently banned Trump for a tweet he post after the 24-hour ban last week was lifted.

Trump had 88 million Twitter followers. The decision to ban Trump has been met with opposition from fellow Republicans, First Amendment advocates, Germany Chancellor Angela Merkel – and now investors.
