Ethics office sending letter to Rod Rosenstein stating that Michael Cohen's payment on behalf of Trump was a debt and may be relevant to "any inquiry" Rosenstein may be pursuing.
The form Trump filed with the Office of Government Ethics past year, which was 98 pages long, contained no mention of the Daniels payment.
A reason for the payment to Cohen was not specified in the financial disclosure that the Office of Government Ethics released, The New York Times reported.
"Today, the President filed his annual financial disclosure report with OGE and it is now under review", a tweet from the ethics office said.
Trump's latest form said the reimbursement was being reported "in the interest of transparency", though it did not have to be disclosed as a reportable liability.
Cohen made a $130,000 payment to porn star Stormy Daniels, whose real name is Stephanie Clifford, shortly before the November 8, 2016, presidential election in exchange for her staying silent about an alleged affair she had with Trump. "Mr. Cohen sought reimbursement of those expenses and Mr. Trump fully reimbursed Cohen in 2017. The category of value would be $100,001-$250,000 and the interest rate would be zero".
The mandatory filing says that "in 2016 expenses were incurred by one of Donald J. Trump's attorneys, Michael Cohen". Apol's letter was released with the Trump disclosures.
In last year's disclosure, Trump reported making at least $528.9 million - a number that appears to mix total revenue from his businesses with income - from January 2016 through April 15, 2017. Trump's lawyer Rudy Giuliani has characterized the repayment as taken from funds paid as a retainer for Cohen's legal services that didn't have to be listed as a debt, according to the BuzzFeed story.
