AKIPRESS.COM - Donald Trump claimed income of more than $557 million over the last year, though the campaign provided few details on the sources of the money.

The presumptive Republican presidential nominee made the assertion on his income in a news release on Tuesday to announce that he had filed his required annual financial disclosure with the Federal Election Commission. But the campaign didn’t release the document, Bloomberg reports.

Trump, a billionaire with interests in real estate, golf resorts and licensing, has campaigned on his business acumen while facing repeated questions about his income, net worth and taxes. Unlike other candidates, he has declined to release his tax returns, saying he will do so after the Internal Revenue Service completes an audit. IRS officials have said there’s no reason taxpayers can’t make their returns public, even during audits.

Democratic front-runner Hillary Clinton’s campaign released her 11-page financial disclosure Tuesday night after Trump’s news release.

Trump’s statement says the $557 million in income “does not include dividends, interest, capital gains, rents and royalties.”

Corey Lewandowski, Trump’s campaign manager, said the campaign wasn’t obligated to provide any more specifics to reporters. “It’s not our obligation to release it,” he said. “It’s our obligation to file it.”

The FEC will eventually make the form itself public, but the agency has as many as 30 days to review it first.
