Twitter and Facebook late Monday flagged a tweet and Facebook post by President Donald Trump in which he called a Supreme Court decision on voting in Pennsylvania "very dangerous."
Twitter added a disclaimer to the tweet saying that its content was "disputed" and "might be misleading."
Trump posted the tweet one day before Tuesday's presidental election.
"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.
The U.S. Supreme Court last week allowed extended deadlines for receiving mail-in ballots in Tuesday's election in Pennsylvania and North Carolina.
Twitter added a label to Trump's tweet reading, "Some or all of the content shared in this Tweet is disputed and might be misleading about an election or other civic process."
Twitter users cannot share the tweet without clicking through the warnings.
Facebook's label reads "Both voting by mail and voting in person have a long history of trustworthiness in the US. Voter fraud is extremely rare across voting methods."
