President Trump's tweet about election security in Pennsylvania tagged by Twitter with election integrity notice: On the night before the election a tweet from President Donald Trump was flagged as "disputed" and possibly "misleading" information because it questioned the security of the Supreme Court decision allowing mail-in ballots to be counted even after official voting is supposed to be over. "The Supreme Court decision on voting in Pennsylvania is a VERY dangerous one. It will allow rampant and unchecked cheating and will undermine our entire systems of laws. It will also induce violence in the streets. Something must be done!" Trump said in the tweet. Election integrity notices add an interstitial that must be clicked through in order for the post to be viewed by users, and diminishes the posts exposure across the platform.
