On the eve of the election, offering a glimpse of the coming days, President Trump tested the boundaries of Twitter’s policies regarding election-related content on Monday evening.

In a social media post, the President strongly criticized the Supreme Court’s ruling allowing Pennsylvania election officials to accept ballots arriving after Election Day, provided they were postmarked on or before that date. The Republican Party had been actively pursuing legal challenges to voting rights in several important states in the weeks leading up to the election, a move widely seen as an attempt to improve the current President’s prospects for reelection.

Twitter responded to the President’s inaccurate statement concerning Pennsylvania’s mail-in ballots by placing a warning label identifying the tweet as “disputed.” The platform also limited engagement with the post by disabling options to retweet (excluding quoted retweets), like, and reply, while still allowing it to be viewed.

“The Supreme Court’s decision regarding voting in Pennsylvania is extremely perilous,” Trump stated in his tweet. “It opens the door to widespread and uncontrolled fraud and will weaken our entire legal framework. It could also incite unrest in our communities. Action is necessary!”

Facebook chose not to remove the identical message when it was shared on their platform, but instead added a notice highlighting the reliability of voting procedures. Within three hours of being posted, the President’s Facebook update had garnered 63,000 likes and 13,000 comments.
