WASHINGTON: President Donald Trump’s threat to shut down social media companies after Twitter labeled two of his tweets misleading sets up a fresh challenge for platforms as they struggle to deal with political misinformation during a toxic election campaign. Livingston said he expects Twitter to narrowly enforce its misinformation policies, dealing only with specific issues such as the electoral process and the coronavirus pandemic. The attacks by Trump and his supporters put “so much pressure (on Twitter) and they are blanching at the thought of taking the next step” on curbing political misinformation, Livingston said. “Twitter will face a lot of backlash and whether they can bear up on this remains to be seen,” Woolley said. Amazeen said Twitter’s actions still fall short of establishing the same kinds of standards in force in most news outlets.
