“My pronouns are Prosecute/Fauci,” Musk wrote on his Twitter account on Sunday.
The message went rival on social media earning 177,000 retweets and 1.1 million likes in less than 24 hours.
“Truth resonates,” Musk added.
He also shared a meme portraying Fauci as the character Wormtongue from the Lord of the Rings.
But White House press secretary Karine Jean-Pierre criticized Musk’s social media remarks as “dangerous.”
“These attacks, these personal attacks that we have been seeing are dangerous on Dr. Fauci and other public health officials as well, they are disgusting and they are divorced of reality,” she said during the daily briefing.
She said the White House would continue to defend Fauci from criticism of his handling of the coronavirus pandemic.
