Sources told CNN that criminal charges against Michael Cohen could be announced before September.
The New York Times reported Sunday that potential charges could come from the more than $20 million in bank loans obtained by a taxi business Cohen and his family own.
Investigators are reportedly looking into whether Cohen misrepresented the value of his holdings to secure the loans and whether he failed to report any income to the IRS.
The Times report also said authorities are determining whether Cohen broke any laws by arranging payments to women who claimed to have had affairs with Trump.
Federal officials, Cohen and his legal team all refused to comment on the Times report. Cohen previously told ABC he'll defer to his lawyer if federal prosecutors charge him with anything.
