Sept. 18 letters to Varney and Leibowitz, spearheaded by Oregon Reps. Earl Blumenauer, a Democrat, and Greg Walden, a Republican, argue the Intel ruling "is the latest evidence of a troublesome trend in Europe toward regulatory protectionism." Other successful U.S. firms have faced hefty fines, are under investigation, or possibly face scrutiny from the Commission's competition directorate, they said. The Intel decision "ignores the reality of a highly competitive marketplace," they wrote in the document initially circulated on the Hill this summer.

Intel, which is the subject of an FTC investigation, was a major contributor to the 2008 races of Blumenauer and Walden and employs more than 15,000 people at Oregon facilities, making it the state's largest private employer. The company also has a workforce of several thousand in New Mexico. Democratic Reps. David Wu of Oregon, Harry Teague of New Mexico, Rush Holt of New Jersey, House Science Chairman Bart Gordon and others signed the letter.
