The Cohen case is unlikely to lead to any legal consequences for Trump while he is in office, experts say, although it could prompt calls for his impeachment should Democrats retake the House in November.
A dispute soon broke out between Cohen and Trump over who would pay the former fixer's mounting legal bills.

At times a bully for a family-run business, Cohen was known for his hot temper as he strong-armed city workers, reluctant business partners and reporters.
