"When we were contacted by the Special Counsel's office regarding Michael Cohen, we cooperated fully, providing all information requested in November and December of 2017," the company said in a statement.

"A few weeks later, our consulting contract with Cohen expired at the end of the year. Since then, we have received no additional questions from the Special Counsel's office and consider the matter closed," the statement said.
