Elon Musk got into a Twitter spat with former NASA astronaut Scott Kelly on Sunday after the billionaire entrepreneur appeared to take another high-profile swipe at the LGBTQ community's use of gender pronouns.
"My pronouns are Prosecute/Fauci," Musk, who took control of Twitter in October, wrote, referring to chief White House medical adviser Dr. Anthony Fauci.
The retired astronaut, who is also the twin brother of Sen. Mark Kelly, D-Ariz., scolded Musk for his flippant remark.
Musk, who in addition to being at the helm of Twitter is also the CEO of SpaceX and Tesla, doubled down in his response Kelly.
On Sunday evening, after his spat with Kelly, Musk was met with a mix of boos and applause when he made a surprise appearance during comedian Dave Chappelle’s show in San Francisco.
