Former Solicitor of Labor Gregory Jacob has joined the Washington, D.C., office of Winston & Strawn as a partner in the labor and employment practice. Jacob served as the Department of Labor’s chief legal officer, the third-ranking official in the department, in the Bush administration.

Last year, during Jacob’s tenure, the department launched a controversial audit of all permanent labor certification applications filed by the prominent New York immigration law firm Fragomen, Del Rey, Bernsen & Loewy to determine whether the law firm improperly instructed clients to contact the firm before hiring U.S. workers. Several months later, after Fragomen had sued, the department called off the audit on the grounds that its own prior rulings on the role of immigration attorneys in the application process were confusing.
