Members of COSAL from across the country gathered at the National Press Club in Washington, D.C., on November 4 to celebrate the organization’s 40th anniversary.
The evening brought together members, supporters, and leaders from the antitrust community to reflect on four decades of advocacy and to recognize the people and partnerships that have shaped COSAL since its founding in 1986.
A highlight of the evening was the presentation of the COSAL Champion of Economic Justice Award to Rebecca Kelly Slaughter, former Commissioner of the Federal Trade Commission, in recognition of her advocacy for consumers, competition, and the rule of law, as well as her defense of the FTC’s independence.
The evening also marked the formal recognition of Sharon Robertson of Cohen Milstein as COSAL’s 2026 President.
For 40 years, COSAL has remained the only organization in the United States dedicated to advocating for strong antitrust laws and effective private enforcement. Its members have testified before Congress, filed amicus briefs in courts across the country, and worked with lawmakers to preserve the tools that allow consumers and businesses to hold anticompetitive conduct accountable.
COSAL thanks every member, sponsor, and supporter who joined the celebration, and looks forward to the work ahead.
