CNN Lou Dobbs - video:Immigration Enforcement Added to Senate Minimum Wage Bill by Unamimous Vote Two senators are pushing to include immigration enforcement in the minimum wage bill because they say wages can only truly be raised in the use of illegal alien labor is stopped in this country. Contractors caught hiring illegal aliens would lose government contract work for up to 10 years under one provision in the Senate's minimum wage bill. Sponsored by Senators Jeff Sessions and Charles Grassley, the amendment passed unanimously last week. According to Grassley (R-IA), "The idea is that the contractors ought to meet the same high standards that the federal government meets, or they should never be doing work for the federal government. The idea is to make sure that illegal aliens are not on the taxpayer payroll." Employers would be exempt from sanctions if they voluntarily verify their workers with the government's basic pilot program. A coalition of 18 business groups criticize the amendment. Among them, the American Meat Institute, the American Immigration Lawyers Association, the National Retail Federation and the Nation Restaurant Association, the National Association of Home Builders, and the U.S. Chamber of Commerce. In a letter to senators, they asked instead for "comprehensive immigration reform legislation."
