US President Donald Trump has revealed that he reimbursed personal attorney Michael Cohen up to US$250,000 (A$332,588) – the same attorney who paid hush money to porn star Stormy Daniels.

A footnote in tiny type on page 45 of Mr Trump's 92-page financial disclosure report says the president "fully reimbursed" Cohen for "expenses" ranging from US$100,001 to US$250,000.

The report says Mr Trump did not have to disclose the payment but is doing so "in the interest of transparency".
