The deal makes official a link between the president and foreign and corporate interests, many of whom rely on Squire Patton Boggs for legal and lobbying counsel. A press release by the firm said it would partner with Michael D Cohen & Associates to “advance the interests” of its clients.

Cohen, a former partner at New York law firm Phillips Nizer, is listed in New York court records as working for the Trump Organization, though the firm Michael D Cohen & Associates was registered as a business on 21 March.
