From the New York Times:

Rep. Rob Portman, Republican of Ohio, was sworn in as the new United States trade representative today following the Senate’s approval of his nomination early this morning…

With record trade deficits and mounting concern in Congress over China’s handling of its currency as well as its violation of international trade laws, Mr. Portman promised lawmakers during his confirmation hearing last week that he would get tough with the Chinese and do a better job of enforcing trade laws.
