The line-up includes the CEOs of the four largest U.S. banks: JPMorgan's Jamie Dimon, Bank of America's Brian Moynihan, Citi's Jane Fraser and Wells Fargo's Charles Scharf.
They will be joined by USBancorp (USB.N) CEO Andy Cecere, PNC Financial (PNC.N) CEO William Demchak, and Truist Financial CEO William Rogers, who run the country's largest regional lenders.
That's a message the banks' executives, lobbyists, and trade groups have conveyed during a marathon of private meetings with key lawmakers over the past few weeks, the sources said.
But bank executives are also wary of growing criticism from Republicans, traditionally allies who have pushed back against heavy regulation, over what they see as Wall Street's increasingly liberal leanings on environment and social issues.
While executives faced some critical questions from Republicans on such issues last year, the pressure will be greater this time, said analysts.
