The organization called on the Justice Department and FEC to “fully investigate” the possible violation.

The Wall Street Journal reported earlier this month that Cohen, an attorney for the Trump Organization at the time and now Trump’s personal lawyer, arranged for Daniels, whose real name is Stephanie Clifford, to receive $130,000 as part of a nondisclosure agreement before the 2016 presidential election.

Cohen used a private company and a pseudonym to funnel the money to Daniels, The Wall Street Journal reported.

Cohen denied to the newspaper that Trump had a sexual encounter with Daniels but did not comment on the alleged payment.

In Touch magazine later published an interview with Daniels from 2011 in which she details her affair with Trump, which she claims happened shortly after his youngest son, Barron, was born.
