Michael Cohen, a personal lawyer to President Donald Trump who started his own firm two weeks ago, has formed a strategic alliance with global legal giant Squire Patton Boggs.

The deal, announced Monday evening, 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's 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 with the New York State Department of State on March 21. Its main address is at 502 Park Avenue, a building in midtown Manhattan known as Trump Park Avenue where the president's daughter, Ivanka Trump, also has an apartment.
