Sacha Baron Cohen is using his celebrity platform to try and silence conservatives, telling Facebook and YouTube that they must not lift their suspensions of President Donald Trump because he represents a threat to democracy.

His ultimatum was echoed by Amy Schumer, who is a cousin of Sen. Chuck Schumer (D-NY) and who supported Joe Biden’s bid for the White House.

Sacha Baron Cohen claimed that the president could “incite violence again” if he is allowed to return to Facebook, Instagram, and YouTube. The British star also used the hashtag #BanTrumpSaveDemocracy.

Facebook CEO Mark Zuckerberg announced that he was banning the president “indefinitely” from Facebook and Instagram, following the storming of the Capitol by protestors. The tech billionaire later said that he was extending Trump’s suspension until at least Inauguration Day.

Facebook COO Sheryl Sandberg said the social media company has “no plans” to lift its ban on President Trump.

Google-owned YouTube said separately last week that it was suspending the president’s channel for at least seven days, citing the “potential for violence.”
