Twitter appended a label to fact-check President ’s tweet about his firing of the nation’s top election security official Chris Krebs.

Krebs’ recent statement that the Nov. 3 election “the most secure in American history” was “highly inaccurate,” the president wrote.

“This claim about election fraud is disputed,” the label read.

Trump announced in a tweet late Tuesday that he had “terminated” Krebs, the director of the Cybersecurity and Infrastructure Security Agency director who had contradicted the president’s claims of widespread voter fraud. 

Krebs changed his Twitter profile bio to “1st Director” of the Cybersecurity and Infrastructure Security Agency followed by “former” to reflect his new employment status and acknowledged his dismissal in a tweet: “Honored to serve. We did it right. Defend Today, Secure Tomrorow (sic).”

Republicans routinely cite anecdotal evidence that their posts are flagged more often. Researchers have found no evidence of systematic suppression of conservative voices or viewpoints. The companies deny any politically motivated censorship.
