Michael Cohen, ex-lawyer for former President Donald Trump, is expected to testify on Monday, Fox News has learned. 

Cohen is expected to be the star witness for Manhattan District Attorney Alvin Bragg and his team for his role in arranging a $130,000 payment in 2016 to adult actress Stormy Daniels to reportedly keep her story that she had a sexual encounter with Trump in the early 2000s. 

Trump, later, made several payments of $35,000 to Cohen, who was his personal attorney at the time. Trump has denied the encounter happened.

Those payments served as the basis for Bragg's indictment of Trump on charges of falsifying business records. Bragg is trying to prove those payments were reimbursements for the payment to Daniels.

But Trump defense attorneys say that the $35,000 payments were "not a payback," but instead, legal payments.

Trump has pleaded not guilty to 34 counts of falsifying business records in the first degree.
