Thanks to some aggressive litigating by a plaintiffs firm, regulators and legislators are reportedly looking into whether military contractor KBR Inc. silenced whistleblowing by requiring employees to sign confidentiality agreements during the course of routine internal investigations.

According to an April 1 story by The Washington Post, two democratic congressmen on the House Oversight and Government Reform Committee have launched an investigation into whether KBR’s confidentiality agreements violate federal laws designed to protect whistleblowing. Back on March 10, the Post reported that the U.S. Securities and Exchange Commission opened a similar investigation into KBR’s activities.
