“A nonprofit watchdog group has asked the Justice Department and the Office of Government Ethics to investigate whether a secret payment to an adult film actress made prior to the 2016 presidential election may have violated federal law because Donald Trump did not list it on his financial disclosure forms,” the AP reports.

The group Citizens for Responsibility and Ethics in Washington lodged a civil and criminal complaint Thursday over the matter.

“The group argues that Trump attorney Michael Cohen’s $130,000 payment may have been a loan to Trump and, if so, needed to be disclosed,” the AP reports. “And CREW noted that special counsel Robert Mueller may also want to investigate because of ‘a similar pattern of potential blackmail’ in personal matters involving Trump.”

“Stormy Daniels, whose real name is Stephanie Clifford, claimed in a lawsuit filed this week that the $130,000 payment made as part of a nondisclosure agreement was to ensure she didn’t share details of an extramarital affair with Trump.” the report notes, adding: “CREW argues that Trump’s 2016 financial disclosure form did not include any reference to Cohen or Essential Consultants LLC, and that if the allegations are true, it should have. Public officials are required under the Ethics in Government Act of 1978 to report all liabilities beyond $10,000 during the preceding calendar year.”
