The Senate unanimously confirmed Stuart E. Eizenstat as deputy Treasury secretary late Tuesday.
Mr. Eizenstat, who most recently served as State Department under secretary for economic, business, and agricultural affairs, is expected to be a major player in the House-Senate negotiations on financial reform legislation.
Mr. Eizenstat was a top economic policy aide to President Carter and is widely credited with shepherding interest rate deregulation legislation through Congress.
He briefly represented a precursor to the Financial Services Roundtable on Glass-Steagall Act reform.
The Senate also confirmed Lewis A. Sachs as assistant Treasury secretary for financial markets.
