dcblogs notes this story about a bipartisan group of U.S. senators that has asked for an investigation into whether companies are firing American workers and replacing them with foreign workers for the sake of cutting costs. "Ten U.S. senators, representing the political spectrum, are seeking a federal investigation into displacement of IT workers by H-1B-using contractors. They are asking the U.S. Department of Justice, the Department of Homeland Security and the Labor Department to investigate the use of the H-1B program "to replace large numbers of American workers" at Southern California Edison (SCE) and other employers. The letter to Attorney General Eric Holder and the secretaries of the two other departments, was signed by U.S. Sen. Chuck Grassley (R-Iowa), chairman of the Senate Judiciary Committee, which has oversight over the Justice Department. The other signers are Sens. Richard Durbin (D-Ill.), a longtime ally of Grassley on H-1B issues; Jeff Sessions (R-Ala.), Richard Blumenthal (D-Conn.), Sherrod Brown (D-Ohio), David Vitter (R-La.), Claire McCaskill (D-Mo.), Bill Cassidy (R-La.), Bernard Sanders (I-Vt.), James Inhofe (R-Okla.). Neither California senator signed on. "Southern California Edison ought to be the tipping point that finally compels Washington to take needed actions to protect American workers," Sessions said. Five hundred IT workers at SCE were cut, and many had to train their replacements."
