Don’t try to tell Mark Mendelsohn that bribery is just another cost of doing business overseas, because he won’t buy it. Mendelsohn is the point man at the U.S. Department of Justice for enforcing the Foreign Corrupt Practices Act, which makes it a criminal offense for any company operating in the United States to bribe government officials in other countries.

During his two years as deputy chief of Justice’s fraud section, Mendelsohn has opened a rising number of formal investigations and overseen a spike in voluntary disclosures. He’s also successfully lobbied for new staff members dedicated solely to FCPA matters.
