The White House declined on Monday to comment on billionaire Elon Musk's deal to buy Twitter Inc TWTR.N, but said that President Joe Biden has long been concerned about the power of social media platforms.
"Our concerns are not new," said White House spokesperson Jen Psaki, adding that the platforms need to be held accountable.
"The president has long talked about his concerns about the power of social media platforms, including Twitter and others, to spread misinformation."
But she said the White House would not comment on an individual transaction.
Former US President Donald Trump said on Monday that he will not return to the social media platform Twitter even if his account is reinstated.
Trump told Fox News that he will formally join his own Truth Social startup over the next seven days, as planned.
"I am not going on Twitter, I am going to stay on Truth," Trump told Fox News. "I hope Elon buys Twitter because he’ll make improvements to it and he is a good man, but I am going to be staying on Truth," Trump said.
