FBI Director James B. Comey’s news conference Tuesday was, by his own words, “an unusual statement.” He gave the public a rare look at the way the FBI conducts its investigations and considers information in making recommendations to prosecutors.

Comey’s key points about the investigation into former Secretary of State Hillary Clinton’s use of a personal email system during her time in office should serve as a reminder to federal government contractors and their attorneys that special care must be given to comply with the law when one is trusted with the government’s information. Attorneys who handle internal investigations and the representation of executives during government investigations can also gain valuable insights from Comey’s statement.
