Big Law's lobbying arms say they are navigating "uncharted" waters after Tuesday's historic vote to remove Kevin McCarthy as speaker of the House of Representatives.

Without a speaker, the House's core legislative functions grind to a halt, leaving client advocacy work on Capitol Hill in limbo at a time when Congress needs to pass annual spending bills. As a result, business for law firm lobbying and public policy practices could slow down, depending on how long the speaker race goes.
