O’Melveny Launches National Security Enforcement Task Force

Our team of former prosecutors and regulators guides corporations, boards, and audit committees through sensitive internal investigations, helping them assess allegations of wrongdoing, make disclosures, and craft new policies to prevent repeat problems. We tailor each investigation to its particular facts, circumstances, and issues while prioritizing efficiency, the preservation of privilege and striving to stay out of the way of day-to-day operations.

We take a comprehensive approach to these engagements, navigating parallel government inquiries, outside auditor diligence, litigation threats, and media strategy. Our strengths include:

  • Board Investigations. We help corporate boards and special committees with independent investigations and advise on steps for remediation.
  • Cross-Border Investigations. We lead investigations involving cross-border activity and leverage our global footprint to conduct local interviews in jurisdictions around the world in native languages and in accordance with cultural norms. We also work with our data-privacy team to ensure compliance with international privacy rules while conducting interviews and gathering data.
  • Whistleblowers. We provide clear, actionable advice on how to navigate whistleblower protections involving both known and anonymous whistleblowers before, during, and after investigations.

Our experience covers a broad array of substantive areas, including:

  • Accounting Fraud
  • Bribery and Extortion
  • Consumer Fraud
  • C-Suite and Executive Malfeasance
  • Cyber Incidents
  • Economic Sanctions
  • Environmental Enforcement
  • False Claims Act
  • Foreign Corrupt Practices Act
  • Health Care Fraud
  • Money Laundering
  • Price and Wage Fixing
  • Securities Fraud and Insider Trading
  • Trade Secrets
  • Workplace Misconduct and Discrimination
