When he announced his Republican run for president a month ago, billionaire businessman Donald Trump said he didn’t need the help of donors. That’s proved true.

Federal documents Trump filed Wednesday show that he has lent his high-profile campaign $1.8 million. In a press release, he set his net worth at more than $10 billion.

The documents show that Trump has not solicited any money for his campaign, collecting only $92,000 from other people. At of the end of June, Trump had about $488,000 left in his campaign account.

Trump is vying with 16 others for the Republican nomination.
