ELON MUSK has called out US President Joe Biden for failing to congratulate his Inspiration4 astronauts on their SpaceX flight.
The four civilians made history and a lot of money for charity when they landed safely back on Earth at the weekend.
It was the first all civilian spaceflight to ever take place.
One SpaceX observer tweeted: “The President of the United States has refused to even acknowledge the 4 newest American astronauts who helped raise hundreds of millions of dollars for St. Jude.
“What’s your theory on why that is?”
To which Musk replied: “He’s still sleeping”.
This phrase has caused controversy as it’s similar to the phrases used by the Republican party and Donald Trump to mock Biden.
Former President Trump would call Biden “sleepy Joe”.
Another SpaceX fan tweeted: “These four American explorers should be acknowledged and applauded by the President.”
To which Musk simply replied: “Absolutely”.
Mr Biden and the White House have still not issued a statement about Inspiration4.
Some people have taken to social media to defend the president and his silence.
One Twitter user wrote: “Dude is busy running a nation during a pandemic. Post-war intelligence briefings. Cybersecurity threats. SCOTUS shenanigans and human rights. Budget and tax legislation.
“Stroking the egos of billionaires isn’t a national priority.”
Others supported Musk by retweeting his comment about sleeping and using “#SleepyJoe”.
