President Barack Obama on Saturday announced three more appointments to the Treasury Department, naming Helen Elizabeth Garrett as assistant secretary for tax policy, Michael Barr to be assistant secretary for financial institutions and George Madison as general counsel. The White House has been repeatedly criticized for failing to fill spots at Treasury while the economy continues to struggle. Several who have been named previously withdrew. The new nominations are in addition to three that were added by Obama in recent days, as Treasury Secretary Timothy Geithner’s senior staff starts to take shape. Garrett is vice president for academic planning and budget at USC and served on former President George W. Bush’s tax reform panel, which issued recommendations that were ignored by Bush. Barr is a senior fellow at the Center for American Progress and at the Brookings Institution. Madison is a former executive vice president and general counsel of TIAA-CREF and a member of its executive management team.
