WASHINGTON, DC (September 12, 2022) – Mercury, a leading global, bipartisan public strategy firm, today announced the addition of Patrick Costello as senior vice president to its Washington office. Costello spent over a decade at the Council on Foreign Relations (CFR) in Washington, where he held a number of senior roles and directed CFR’s interactions with policymakers and the diplomatic community, most recently as director of Washington External Affairs.
Costello will join Mercury’s bipartisan federal lobbying team and will lead its NGO/Think-Tank engagement practice
Costello is a recognized expert in U.S. foreign policy, trade policy, business diplomacy and the domestic politics of American foreign policy. Costello also regularly consults with the policymaking community and stakeholders on a wide range of foreign policy and economic issues. He is frequently sought out by individuals, institutions and companies to advise them on how to maximize their influence and impact in Washington, and writes a monthly column for the international business community in Italy.
“Patrick served as the chief liaison to Washington for arguably the most elite think tank in the world,” said Mercury CEO Kieran Mahoney. “He will be indispensable in helping our clients navigate high-level policy challenges, and we are pleased to announce him as the newest member of our team.”
Costello most recently served as the chief executive officer of the American Security Project (ASP), an organization focused on fostering a bipartisan consensus to confront international challenges, where he provided day-to-day management of organizational strategy, internal policy formation and stakeholder engagement, and served as the public face of ASP to outside constituencies. Costello also served in the office of former Congressman Jon Porter (R-NV), fulfilling a variety of policy and communications roles.
“Joining Mercury’s outstanding bipartisan team is a natural extension of my experience in working in Congress and in the international business and foreign policy sector,” said Costello. “I am looking forward to helping clients navigate the Washington policy ecosystem and advise them as they manage risk while working to achieve their business objectives.”
