Former Utah Solicitor General Tyler Green is joining the Washington-area litigation boutique Consovoy McCarthy, the firm widely known for its advocacy for President Donald Trump in his effort to stop U.S. congressional investigators and New York prosecutors from obtaining his financial records.

Green, a former clerk to Justice Clarence Thomas during the 2009-10 term, is a partner in the now 12-lawyer firm that was started in 2014 by William Consovoy and Thomas McCarthy, formerly classmates at George Mason University School of Law. Green will be based in Salt Lake City.
