The United States economy has overcome the financial crisis that President Barack Obama faced on taking office in 2009, but more progress is needed, Treasury secretary nominee Jack Lew told the US Senate on Wednesday, according to dpa. "We're in a better position today, but the work to create a sounder economy and a safer world remains unfinished," he said in a hearing before the Senate Finance Committee. "Our top priority is to strengthen the recovery by fostering private sector job creation and economic growth while we make sure our economy remains resilient to the headwinds from beyond our shores." Obama last month named Lew, a long-time Washington insider, to succeed first-term Treasury Secretary Timothy Geithner, who left office on January 26. -- SPA
