The U.S. president threatened to shut the platform down after it placed a warning on two of his tweets that falsely claimed mail-in ballots would lead to voter fraud. Twitter determined these tweets to be a violation of its “civic integrity policy,” which bans users from “manipulating or interfering in elections.” The tweets now feature a light blue exclamation point icon with the message “Get the facts about mail-in ballots.” (The Wall Street Journal)

Talking point: The move marks one of the first cases of the company enforcing its policy of labeling tweets by public officials that may violate its rules. The decision also sets Twitter apart from Facebook, which didn’t take any action on similar posts on its platform. A standoff has now ensued between Twitter and Republican leaders, who suggested the company should lose its liability protections. “The law still protects social media companies like Twitter because they are considered forums not publishers,” Senator Marco Rubio tweeted. “But if they have now decided to exercise an editorial role like a publisher then they should no longer be shielded from liability & treated as publishers under the law.”
