U.S. Treasury Deputy Secretary Robert Kimmitt said he would not comment on the weakness of the U.S. dollar on Saturday after the currency slid to a record low against the euro on Friday.

The U.S. economy expanded at a sluggish 1.3 percent in the first quarter of 2007, the Commerce Department said on Friday, reflecting declines in the housing market and a pickup in inflation. It was the fourth consecutive quarter of sub-par growth in the world's largest economy.
