Homeland Security chief Michael Chertoff is blasting the U.S. Senate for failing to pass an immigration bill, and claims the federal government doesn't have the ability to enforce laws when it comes to illegals working in America. "We're going to continue to enforce the law. It's going to be tough," Michael Chertoff said. "We don't really have the ability to enforce the law with respect to illegal work in this country in a way that's truly effective."
