The Obama administration announced a series of appointments to the Treasury Department on Saturday, helping fill out the ranks of Secretary Tim Geithner's cabinet agency.

President Obama named two assistant secretaries -- Helen Elizabeth Garrett (Tax Policy) and Michael S. Barr (Financial Institutions) -- as well as nominating George W. Madison as the Treasury's general counsel.
