Twitter later added warning labels to Trump’s post reading, “Get the facts about mail-in ballots.” The linked labels lead to a Twitter article with a headline that reads, “Trump makes unsubstantiated claim that mail-in ballots will lead to voter fraud.”

The message under the headline reads: “On Tuesday, President Trump made a series of claims about potential voter fraud after California Governor Gavin Newsom announced an effort to expand mail-in voting in California during the COVID-19 pandemic.

“These claims are unsubstantiated, according to CNN, Washington Post and others. Experts say mail-in ballots are very rarely linked to voter fraud.”

The article also includes three points under the title “what you need to know:”

• “Trump falsely claimed that mail-in ballots would lead to ‘a Rigged Election.’ However, fact-checkers say there is no evidence that mail-in ballots are linked to voter fraud.
• “Trump falsely claimed that California will send mail-in ballots to ‘anyone living in the state, no matter who they are or how they got there.’ In fact, only registered voters will receive ballots.
• “Five states already vote entirely by mail and all states offer some form of mail-in absentee voting, according to NBC News.”

The Twitter article compiled excerpts and links to articles from CNN, The Washington Post, The Hill, and other media outlets. The article also has a running list of other Twitter users’ posts that appear to disagree with the president’s message about mail-in ballots.

Trump 2020 Campaign Manager Brad Parscale said in a statement that Twitter has a “clear political bias.”

“We always knew that Silicon Valley would pull out all the stops to obstruct and interfere with President Trump getting his message through to voters,” Parscale said.

“Partnering with the biased fake news media ‘fact checkers’ is only a smoke screen Twitter is using to try to lend their obvious political tactics some false credibility. There are many reasons the Trump campaign pulled all our advertising from Twitter months ago, and their clear political bias is one of them.”
