Throughout Election Day, right-wing influencers and Republican officials have pushed the baseless conspiracy theory that Democrats are attempting to commit voter fraud and steal Pennsylvania from President Donald Trump .

We are up BIG, but they are trying to STEAL the Election, Trump tweeted just before 1 a.m. Wednesday. We will never let them do it. Votes cannot be cast after the Polls are closed!

False, misleading and out-of-context videos and claims about supposed voter intimidation and other legal violations have reached millions of people on social media. Twitter has appended misinformation warning labels to tweets from the Philadelphia Republican Party and the presidents director of Election Day operations, Mike Roman.

The effort to drive claims of election fraud closely aligns with Trumps vow to send lawyers into Pennsylvania to contest the result, as he pushes the fact-free narrative that Democrats are conspiring against him to rig the election. These false allegations from conservative activists and leaders clearly aim to taint the results out of Pennsylvania a state that could decide the election.

On Tuesday alone, tweets containing #StopTheSteal a hashtag used to accuse liberals of stealing the vote had been retweeted more than 43,000 times by 6 p.m., according to an analysis by First Draft , a global nonprofit that researches misinformation.

The hashtag started rapidly gaining traction on Election Day after Will Chamberlain, editor of the conservative magazine Human Events, used it while tweeting a video seemingly showing a worker at a polling station in Philadelphia denying admission to a certified Republican poll watcher.

Philadelphia city officials quickly confirmed that the worker in question simply made a mistake due to a misunderstanding of the law and that the poll watcher was later admitted to the polling station, ProPublica and other news outlets reported. But that didnt stop Chamberlains tweet which remains pinned at the top of his profile with #StopTheSteal from going viral. The video now has more than 2 million views on Twitter, and has been shared widely without context.

In an article headlined The Steal Is On, the far-right publication Breitbart cited Chamberlains video as evidence of partisan, illegal activity. Donald Trump Jr. shared the article with his nearly 6 million Twitter followers.
