Tech billionaire Elon Musk , the richest person in the world, is donating to a political action committee working to put Donald Trump back in the White House, according to reports from Bloomberg and The Wall Street Journal .

Musk who oversees SpaceX, Tesla, and X, the social media platform formerly known as Twitter has committed to donating $45 million a month to America PAC, a pro-Trump fundraising group established in May, people familiar with the matter told the Journal.

The news comes days after Musk formally endorsed Trump for president.

Bloomberg was the first to report on Musk donating to America PAC on Friday, saying it was an unknown but sizable amount.

A donation from Musk could make a massive difference in a tight race, though Trump already outpaces President Joe Biden in fundraising.

Contacts for Tesla, Trump and America PAC did not immediately respond to HuffPosts requests for comment on Bloombergs report. The PAC is next legally required to disclose its donor list on July 15.
