On Tuesday, Michael Avenatti, a lawyer for Stormy Daniels, the adult-firm star who was paid $130,000 by Cohen to keep quiet about an alleged affair with Trump before the 2016 election, released information on Cohen's banking history.
The banking information shows Cohen was hired by a US-based affiliate of a Russian company owned by Russian billionaire Viktor Vekselberg, who was recently sanctioned by the US government.
The information released by Daniels' lawyer also showed payments to a Cohen company Essential Consultants, from other businesses, including the US telecommunications company AT&T and the pharmaceutical company Novartis.
