Squire Patton Boggs has ended its formal working relationship with US President Donald Trump’s personal lawyer Michael Cohen, following an FBI raid on Cohen’s offices in New York.

“The firm’s arrangement with Mr Cohen reached its conclusion, mutually and in accordance with the terms of the agreement,” the firm said in a statement. “We have been in contact with federal authorities regarding their execution of a warrant relating to Mr Cohen. These activities do not relate to the firm and we are in full cooperation.”
