WASHINGTON — Twitter flagged all of President Trump’s early-morning tweets on Saturday as disputed and potentially misleading after he made baseless claims about election irregularities.
In a series of posts, Mr. Trump focused his ire on Pennsylvania, where a loss in the state would seal his fate as a one-term president. Mr. Trump was trailing former Vice President Joseph R. Biden Jr. by about 28,000 votes when he tweeted.
Within an hour, Twitter had put a warning label on all four of the tweets, saying that the content of his claims “might be misleading about an election or other civic process.”
Twitter has grown increasingly aggressive about flagging Mr. Trump’s false statements even as the president, in the days since Election Day, has spread false stories about “illegal ballots” and has demanded that local officials in several states stop counting ballots prematurely.
