Elon Musk and veteran astronaut Andreas Mogensen were exchanged in a heated debate on X after the latter called the tech mogul out for 'lying' about NASA astronauts Sunita Williams and Butch Wilmore. Andreas Mogensen called out SpaceX CEO Elon Musk for claiming Joe Biden abandoned Sunita Williams and Butch Wilmore in space for "political reasons". Musk was quick to counter, calling Mogensen an "idiot and retarded".
