US media outlet Bloomberg says Elon Musk has donated to a political group working to elect former President Donald Trump to the White House.

Bloomberg on Friday cited people familiar with the matter as saying the US entrepreneur donated "a sizable amount" to the group. The exact figure was not indicated.

In March, Musk posted on his social media platform X, "Just to be super clear, I am not donating money to either candidate for US President."

Bloomberg said neither Musk nor the Trump camp offered comments on the donation.

Bloomberg referred to the move as "a major gambit by the world's richest person to make his imprint on the US political landscape."
