The political website RealClearPolitics never projected a winner in the presidential race in Pennsylvania, an editor and co-founder of the site tweeted on Monday, debunking claims by allies of President Trump that it had somehow changed its position.
"This is false. We never called Pennsylvania, and nothing has changed," RealClearPolitics editor Tom Bevan tweeted.
He retweeted a message from former New York City Mayor Rudy Giuliani, one of the people spreading false information online that RealClearPolitics had called Pennsylvania for Democrat Joe Biden but then pulled that call back.
The idea that this had happened exploded on social media Monday evening, leaving many people confused as to whether the influential political website was suggesting the result in Pennsylvania was in question.
Every major news network and The Associated Press have projected Biden as the winner of Pennsylvania, where counts show him leading more than 45,000 votes.
President Trump is challenging the results, insisting without any clear evidence that the election has been stolen from him.
Trump also trails Biden in the states of Nevada, Arizona and Georgia. Networks have projected Biden as the winner of Nevada, and Fox and the AP have projected Biden as the winner of Arizona.
Trump would need to flip at least three states to change the outcome of the election.
Former White House press secretary Sean Spicer also claimed that RealClearPolitics rescinded its call that Biden would win Pennsylvania, but later clarified that it never called the state.
Major news networks and the Associated Press declared Biden the winner shortly before 11:30 a.m. on Saturday after he was projected to win Pennsylvania, but the president has not conceded defeat.
Trump has baselessly claimed that the election is being stolen from him, and his reelection campaign has mounted legal challenges in several battleground states where he is behind.
