Hazen Marshall, former policy director for Senate Majority Leader Mitch McConnell (R-Ky.), and Monica Popp, former chief of staff to ex-Senate Majority Whip John Cornyn (R-Texas), are teaming up to launch a new lobbying shop, Marshall & Popp.

The two aides left the Senate at the end of the year to register as lobbyists and officially launch the government affairs and consulting firm. The firm’s goals are to promote strong policies, adjust to dynamic political environments and help clients navigate Washington’s complex process and procedures.

“[I was a] tax and budget guy for the large majority of my career so that’s still kind of my wheelhouse,” Marshall said.

While they are currently barred from interacting with the Senate, they hope to provide counsel on Senate procedure more broadly for their future clients.

“Working in the Senate is the best way to know the Senate,” Popp said.

Marshall added that providing counsel on the budget process is particularly important.

“I found both working on and off the Hill, there’s a real need from a lot of clients to understand how the process has helped them or how it can hurt them,” he said.
