Legislative & Public Policy

We operate at the intersection of public policy and law, helping clients find solutions to complex problems that involve interacting with the federal government. We represent a cross-section of the world's most recognizable companies, associations, and organizations. We focus on healthcare/life sciences, financial services, energy, trade, technology, federal funding, foreign sovereign representation, and education. The issues we tackle require deft political handling as policy battles impact other areas, such as litigation, pending financial transactions, corporate risk management, business reputation, the media, and the consumer marketplace.

During the COVID-19 pandemic, we are working with clients to address unprecedented legislative and public policy challenges, including: (1) designation as essential industries; (2) maximizing access to capital lending facilities administered by the Treasury Department and the Federal Reserve; (3) aiding in eligibility for the SBA's Paycheck Protection Program; and (4) securing billions of dollars in direct and indirect aid for various industries such as hospitals, air freight cargo providers, and childcare providers.

  • Working with top-rated lawyers in a number of other practice groups at the firm, our team is able to help clients address multifaceted legal and policy problems from a variety of perspectives, leading to better and more comprehensive solutions.

  • With three of the youngest lobbyists on The Hill's recent top "Hired Guns" lists, we have our finger on the pulse of a rapidly evolving legislative environment that requires new strategies to succeed.

  • We are the largest law-firm based lobbying practice where a majority of lobbyists are women at a time when the number of women in Congress and in key decision making positions in Washington is at a record high.
